As a person who's been in the closet for the last 4 years, I share the same struggles as you, I'll see someone sharing their transition story/timeline on other social media platforms and get a mood hit instantly.
Seeing other transgender people is basically a reality check for me, reminding me of the harsh reality I live in, the person I actually am, and what it can be.
Hang in there, probably everything will be alright!!
Yeah, I dissociate a lot, haha.
Anyways, they will get used to you doing stuff you like, they usually need to get past their trans and other stigma (which can take a really long time). If your city has a support group for parents of queer children, you can try signing them up.
