Hi Amrisa,
I guess you are nearing the cross roads with these friendships, that in some time soon, may undergo a massive transition within itself, due to your transition. What I'm saying is, that for very change you make towards your final goal, will determine and test the resolve these friendships can sustain.
This will be the litmus paper to your future support network. Bearing that in mind, now may be a good time to start looking for a support network that will out last your transition and propel you into what may seem an unbelievable future for you.
You could 'test the water' by asking each individually, how your wardrobe affects your relationship with them. You could also add, how would they feel if you dressed more appropriately to the gender of your choice, and observe their reaction. For this you'll know, who is for you, and who isn't.
Hope this helps to some degree, and it works out for you. Embrace and enjoy your journey. Let us know how it works out.
Be safe, well and happy
Lotsa huggs
Catherine
