I saw a therapist for a short while this year; the last time I saw him was about 3 months ago. I made it very clear that I was only there to get my letter for T. I'd seen a different therapist before this one for closer to 5 months, and he flaked out on me when I asked for a letter (even though he said he'd write me one

). The second therapist wrote me a letter, my mom scheduled an endo appointment for me (I'm under 18 and afraid to make phone calls, lol), and now, roughly two months later, it's almost time for my first endo visit.
I called my mom a bit ago to work out some school stuff, and the conversation turned toward when my appointment was. She told me that she already got a copy of the letter from my therapist, and he recommended to my endo that I stay in therapy. Let me make it clear that therapists make me VERY uncomfortable. The first one I went to swore he'd worked with trans people, and then continued to call me by the wrong name and pronouns. The second therapist called me the right pronouns, but thought that it was okay to use my birth name during certain parts of therapy sessions. When I politely told him that it made me uncomfortable, he acted like I was totally over reacting. He also asked me when I "stopped playing with barbies, etc." and I told him that I felt like it was a trick question, as I'm mostly gay, and I know a lot of gay boys who had no problems playing with dolls when they were younger.
He kind of flipped out.

I don't think he was angry, but he got really weird when I told him I was gay. Then he started asking me what I meant by that; did I want to be a man, or did I want to be with men? As if these are two mutually exclusive things (not to mention, I don't "want to be a man", I am a man. I want other people to see me that way too).
I don't really feel comfortable talking to him, especially since he was trying to get me to guess who the other trans guy at my school was since the other guy went to see him too. NOT VERY PROFESSIONAL!!!

Does anybody know if I have to go to therapy just because he recommended it? Would it depend on how my endo feels about it? I'd rather not go if it can be avoided.
Please answer if you can! My endo appointment is Tuesday, and this therapy thing is making me really anxious.
(On a positive note, HOORAY TESTOSTERONE!!!
