Late to the party but I hear you.
I was lucky to transition in a relative bubble free from many naysayers. Family, friends, job all supportive. Only once in nearly 10 years (until this past fall) did I encounter discrimination and negativity. As I said, lucky.
Unfortunately that crap hit the fan when my doctor was fired. I had just been seen and was unaware. I was made aware when my prescription for Testosterone ran out and none of the other doctors "were comfortable" prescribing it. Appointments to talk to them were cancelled and not rescheduled. Receptionists were trying to be helpful but I doubt they knew the real reason I was getting the run around. Finally one of the doctors there filled it and said I had 3 months to find a new doctor.
Then, I discovered a long-time friend and mentor went off on a public facebook transphobic tirade aimed at trans kids (insert all of the negative right wing anti-trans propaganda here). No reasoning with her. It was nasty. She is now an ex friend.
So thanks to that I've read quite a bit of the stuff you (the OP) have been reading. It's nasty.
I will say:
1) It's great that you have questions. Ask lots of questions! You need to live YOUR life, whatever that is.
2) Are you trans? That's a question only YOU can answer, and sometimes you need the help of a good therapist to sort that out. Not a therapist that will just be a yes man, but one that will help you explore things on a deeper level. Do you have any other mental health issues? Always worth exploring.
3) Is transition right for YOU? That's for you and you alone to determine. Don't transition because your friends did, or we did, or your therapist thinks you should. You need to make that decision for yourself, because you feel that it is the best thing for YOU.
4) If you think transition is right for you, take baby steps if you need to. Clothing, hair, mannerisms, name, pronouns, all easily reversible if you find it doesn't fit. Hormones, again, baby steps and see how you feel. Everyone's path is different, even though we share a lot in common.
5) If transition is right for you, then you need to do what YOU need to do. Not what your Mom wants you to do, or your Pastor wants you to do, or sadly, even what your SO or spouse wants you to do. Be true to yourself.
6) There is discrimination. There will be heartache. Hearing and reading about transphobia is a huge downer, and many of us are feeling the effects of the negativity with the current state of the country. Exposure has been great; but now that people know we exist they're quite happy to try to tear us down. It's not a path for the faint of heart.
7) Please stop listening to the naysayers. Sure, find out about all of the side effects of hormones and surgery before undergoing treatment. Know the negatives. Only transition when the positives outweigh the negatives, or it's transition or die. I risked everything, as we all do, but I was lucky. Many people lose everything. And that's a hard thing.
Good luck in what you decide. Take what you've learned but go read positive sites. Not necessarily trans sites. This is something I came across a few days ago. She's not trans, but what she said resonates with me.
