Sorry I know this is long

I have condition that affected my development at puberty, a form of Klinefelter's Syndrome (xy/xxy). This caused me to develop gynecomastia at puberty and left me with underdeveloped genitalia, wide hips and no muscle development.
I was routinely ridiculed for my appearance and beaten by bullies during middle and high school. I became severely introverted and withdrawn with little confidence and no self-esteem. I did see two doctors in my late teens / early 20s, but no diagnosis of KS was made at that time, not until many years later. My testosterone was on the low end of the normal range, but still normal, and it was determined I had a micropenis and gynecomastia (which at that time was about a B cup).
I always felt I identified as female for as long as I can remember, but I sometimes wonder if I would have had those feelings if I developed normally. I knew I could never please a girl with a micropenis, and I've never been in an intimate relationship and only have had a few friends my entire life. I'm very quiet, timid and withdrawn. I felt worthless as a human being and still do to now. The world seems to evolve around sex and relationships and I feel I was cheated out of experiencing the basic aspects of life. I lost the few childhood friends I had in my early twenties when they married. People just assumed I was gay because I've never been in a relationship with a girl. I just hate people who make assumptions, but I felt I could not be open about the real issues affecting me because people would see me as a genetic freak or a leper. I was able to drudge on through life for a while by focusing on my work and hobbies, even though I've always felt severely depressed and isolated.
I became an alcoholic in my late 20s. I was still living with my parents then. I finally moved out and bought my own house when I was 30 and stopped drinking. It was then I was able to truly be Jessica. I ordered a new wardrobe and was Jessica when home. It was my safe space to be me. I knew I truly wanted to be a girl and I wanted SRS. There was a big problem though, I'm too tall. Another symptom of KS is tall stature, and I was 6ft 4in and around 185 pounds. But after several months of living in my new house alone, I began feeling severely depressed again, and extremely lonely, isolated and suicidal. I had no friends, and nobody to talk to about any of my issues. I reached out to the TG community on several forums. I made a post under the name sadgirl with my life story up to that point. This was about 14 years ago. I made several friends I communicated with online. They tried to be reassuring about being TS and 6ft 4in. But I kept beating myself over the head regarding my height and other features that weren't very feminine. I had become jealous of others. Anyone shorter than me would have a better chance of passing. It was just hopeless. People who developed normally as men and have sex and relationships as men would also get to experience being a girl as well, while I could be neither. Just a mixed up freak doomed to be alone.
I began self-medicating with hormones around this time. I was suicidal and didn't care about the dangers. I did make several close online friends in the tg community, including my best friend Wendy who lived 2000 miles away. They tried to encourage me but I still never built up the confidence to leave my house dressed.
As time went on I gradually just gave up. I couldn't get past my height. I knew I would never pass being 6ft 4in and would have a more difficult time being accepted. It would take a lot of confidence to pull it off and I have none. I had vowed to off myself if I did not make significant progress with Jessica before I turned 40 and here I was 39. I was planning my suicide and around that time my parents pushed me to adopt some feral kittens that were living behind their house. I ended up adopting two kittens. They gave me a reason to live. Soon after I phased out the hormones after self-medicating for 8 years. I tried to block the sadness of not being able to be Jessica from my mind. I had gynecomastia surgery a few years ago. I was torn. I was embarrassed to be out in public as a guy with B cup boobs, and had been wearing chest binders for several years which were uncomfortable. But I did enjoy having boobs when dressing as Jessica. The pain of not being able to be Jessica full time was too much and I just didn't want people to see me as a freak, so I had the surgery. To top it off I ended up purging most of my girl wardrobe, something I now regret

Now I'm finding myself losing my best and only friend Wendy. I've lost contact with everyone else. We've chatted online almost every day for the past 14 years, gaming online together and streaming movies to watch together online. It's like she was in the house with me even though she wasn't. She is the only reason I didn't off myself in my 30s and the only reason I've kept living. She did visit me at my house on three occasions over the past 14 years and stayed several months total. Probably the best times I've had in my life. She had stroke two years ago though and her health has been declining. I'm in my 40s and she is in her late 60s. When I lose her I will be completely alone and isolated from society.
I don't know how to pick up the pieces or where else to turn. I feel I don't fit in anywhere. I'm extremely suicidal at the thought of being completely alone. My whole life has been a waste and I never got to experience being in an intimate relationship or have even sex. After my gynecomastia, surgery I'm basically just a 6ft 4in "guy" with a micro-penis that no woman or gay man would want. I feel I have no choice but to commit suicide. I've been planning my methods but afraid I will end up failing at offing myself and be even worse off than I am today. My two cats will die without me but I don't know what else to do. The thought of being completely alone and isolated from society is too much for me to handle. What's the point of living life if you have nobody to share it with? It's just too painful being in an empty house alone with nobody to talk to, not even online.
