Kenz most of all I think you need to tell your parents. If it’s got to the point where you and others are noticing changes in your behaviour then you need to tell someone.
I kept my gender dysphoria, phobias and other problems to myself at your age and didn’t let the cat out the bag and repressed it. I wish I had told folks back then how I was feeling.
As it stands my mother is claiming she would’ve been receptive back then. Now I’m in a position no one wants to be in where dependants are involved. All I can say is if this is coming to you now it’s with good reason. Don’t under estimate how receptive your folks might be.
