Hi Kayla,
For me, dysphoria is something that started out so small, just a wisp of thought, almost indistinguishable from the background noise in my everyday life. Yet the wisp grew over time into sporadic thoughts, conscious need and even then, I fought and refused to listen. Then, came the dressing, at first, just a little and it quieted the thoughts, the need, for a while. Yet, it refused to go away, with each passing time I gave in, the need became more until no matter what I did, it never left. Now, I have given in and recognized what I really am.
My best thought is that because you cannot let the need to be Kayla out all the time, the need comes and goes. Given your situation and until you can do more, Kayla coming and going isn't bad. It is very hard to be her and not be able to express as her. I beleive that you should keep trying to get counseling and to talk with your parents. Once you get to where you can express as her, she'll be there always.
I wish I could think of more.
Hugs,
Jen
