I've had a general aversion to therapists and therapy myself for quite some time. I was forced into therapy in middle school, and twice again in HS, because the teachers and counselors made my mother take me - this was all before I connected any of my personal issues to being transgender. The first two times I lied through my teeth to tell the therapist what she wanted to hear so I wouldn't have to go back. I hated being a burden on my folks, and my mom did nothing but complain about having to take me to the sessions. Then, the second time I got sent in HS, I actually started to open up to the therapist, but then my father decided I was "all better" and I didn't need to see the therapist so frequently, and when it came time for my next appointment, a big snow-storm hit and my mom decided she wouldn't take me, and my folks decided I didn't need to reschedule.
Then, I ended up in therapy again a little over a year ago, because I had a nervous break-down and was having constant anxiety/panic attacks. I decided that I wanted to discuss my gender issues, because I was aware of them this time, but the therapist that I could afford to see said she didn't have much experience and just gave me a list of some outside resources (that I couldn't get to anyway).
Now I'm away at a new school, and there is a counseling service provided for free to all the students. I was intent on steering clear of the counseling services, but I ended up having a couple of panic attacks again, and my insomnia got really bad one weekend (I went 86 hours without being able to sleep) so I went to the clinic for sleep aids, and the doctor said I also needed to talk to a counselor to deal with the cause of my insomnia and anxiety. So, once again, I was kinda pushed into it, but it's turned out to be for the best, because I finally have someone to talk to about TG issues, and it has given me the courage to start moving forward.
So... I guess my point is that I always have a lot of difficulty with therapy/counseling - I've always been a nervous wreck the first appointment - but it is worth it to keep trying and keep moving forward.
That's my experience with therapy/counseling thus far.
