Cut off parents

I cut my parents off due to not wanting to deal with their drug addiction an all the drama that comes with it. My parents have been off and on drugs since I was a baby so my whole childhood was affected because of it. Any tips on how to deal with the emotions that come with cutting off parents.

Part of me feels a bit lonely because I did talk to my mom quite a lot. I also live in across the country away from the rest of my family. The other part of me feels like a weight has been lifted off my shoulders. I’m struggling with both those feelings

btw I do have a therapist an  psychiatrist before anyone says therapy
