Hi there,
welcome to PC!
I find that focusing on a diagnosis is often not very productive. Your story tells more about you than any label could.

PC is a great place to share. It helps to exchange some opinions and experiences with others here. I was very isolated when I grew up and I wasn't really allowed to have an opinion or to voice my truth. So it feels great to have a place where people share their stories and give their opinions. Usually people on PC don't judge and ask a lot of questions.

I am 26 and I also struggle with family problems and depression/anxiety/weird conditions that don't make sense to me or anyone else. Some of the therapists that I have talked to so far also used the "box metaphor" to make it seem less like an endless pile of problems. So I have an abuse box for example, but my experience is that the problems don't just always stay put there. My traumatic past influences my behaviour in many ways and if it were just so easy. Still struggling

I hope you find the support that you need and can relax a little bit and focus on your own life. Sounds like you have been responsible for way too long.
Hugs!
