In my opinion people worries about things they shouldn't worry about.
When you come out of the closet, the reactions are unpredictable.
You can find support from people you never expected it.
But, one way or another it's not in your hands, you can only tell and wait what their reactions are.
Nevertheless, what the reactions are, it won't change anything.
You're a tg and that won't change, the only thing what can change is the support you can get.
But that wouldn't stop you from your journey to transition, right?
So, just be yourself, tell what your feelings are and hope for support.
There can't be a judgement coz it's your life and you have to make it a pleasant life, nobody else does.
Good luck and I hope the reactions will be positive
