Help please!!

So here’s a little background. My parents divorced when I was 5 and I stayed with my mom except for every other weekend. When I was 10 my dad went for it to be the other way around but now we just go week to week. Because of all of that I have terrible anxiety and a small case of PTSD. I’m old enough that I can choose to live with my mother and I have told him that I want to and he said that we would talk about it again but he hasn’t said anything to me since... What should I do? Should I just go for it??

Age: I’m 15 but everyone I know (adults) tell me I act 30.
