I'm guessing that your fears are just now starting to show up because things are becoming real? Like, you said you have dreamed about being a girl, but dreams are easy, but now things are progressing, starting the journey, its becoming real, and it is hard, scary, unknown. I know that is scary for me too. If you are like me, probably had these feelings forever and did everything you could to keep em hidden, soon that is gonna change, so I think is normal to be scared.
Are you not going to the support group because you are scared or some other reason? Again, if you are like me, it is new, therefore unknown and scary. I always get like that lol..After you do it though, becomes less scary each time. Off topic a bit but, when I first wanted to start on hair removal, wanted to call and make an appointment, couldn't...so I thought, hmm, I will drive there and make one in person! So I drove there, parked, and sat in my car, too scared to go in....After like 30 minutes of trying to get the courage to do so, realized I couldn't, so I called! Called from the parking lot LOL! They didn't even answer when I did, but called me back a bit later since somehow I managed to leave a message, I think. First time going in and meeting her and starting, I didn't think would happen on first meeting so wasn't prepared really but guess worked out good cuz didn't have time to worry or chicken out of it, but now have no problems going and getting it done.
The best thing I can think to say is just take things slow, take baby steps. One thing at a time. Maybe next time they meet, give yourself a goal of just driving to the location, not going in, just driving there. Maybe then you will be able to think bout going in and attending, if not, try again next time. Just work yourself up slowly.
