Hi Stuck,
I'm Kristen. Welcome.
I'm not going to insult you, or tell you I know how you feel. I heard something yesterday that's been resonating with me, and I think it's applicable here: "When you've met one trans person, you've met one trans person."
So while your story and life experiences have been your own, what I can say is that I've noticed some similarities in what you've written here, and some of my own experiences in life.
A part of me can't believe I'm writing a reply here, since I still get these feelings and at times feel things similar to what you seem to be feeling. Another part of me feels that that's the reason I am writing here.
I don't know if I can offer you any advice that's pertinent to your situation. What I can share is a viewpoint that I try to fall back on when I feel worthless...small...like a pariah...you get the idea... I try to grasp the fact that we live in a world where there are almost 8 billion others. I'm not the best of them, but I know I'm not the worst. I also know that there are those within that 8 billion that can see beyond what the masses seem to brush off or allow themselves to fall victim to their own short attention spans or selfishness.
I've been going through ish lately. Home. Work. Public life. Life is great right? It may not seem so, but when it is, it's something to savor, which I have no doubt you will do when it comes your way. It may be difficult or impossible to see, but it will come your way. You don't know me, so I won't ask you to trust me. Read over what I've wrote, analyze it, and trust your own judgement. You know it will come your way. I know you do.

You probably won't believe it, though I hope you do, but Jamie D is spot on when referring to your strength and ability to cope. If Jamie D and the other respondents here can recognize that, there. are. others. that will too. We're obviously glad you made and carried out the conscious decision to come here. One thing I CAN say about you, is that you still have hope. Your OP shows that. So, with that being said, it seems to me that you are a "valuer," as you said in your post above, right?
For me, I think of myself as a big catcher's mitt...I used to catch all the hate people threw at me...and I held onto it. I let it corrode me from the inside out. I still do, but well, the mitt is shrinking day by day...and...I'm learning to duck! LOL
Again, I cannot tell you what applies in your case, but based on the similar feelings and situations I've felt in the past, I think knowing that you have a friend that actually gives a ish is gonna be great. Whether you like it or not, you've got some now!!!!! So there!
Now get your post count up will ya?
(((HUGS)))
