Many of my issues seemed to get worse when I'd moved out of my dad's the first time. Some things improved, like I was happier. All in all my anxiety got worse. It was like my fear increased with safety because I wasn't accustomed to being safe like that.
I'm not sure if this is the same thing as what you're dealing with. If it is, I'm not sure why it happens. I guess I wrote this to try and help you feel less alone. When I was going through that, my support at the time had to be patient with me. It can take some time.
