I have mental health issues as well and let me tell u it's exhausting trying to distinguish if it's ur addictions or mental health causing the issues but as u well no having an addiction on top of ur mental health issues makes them worsen. U need to stop. And as far as relationships go my saying is "no one can love u until u love yourself" n it's true. When I date someone I get crazy doubts like when they compliment me I don't believe them or I think they have ulterior motives, I get jealous bc I don't think I'm good enough n I start all the problems but I can't help I feel that way bc I don't believe I'm good enough so until I do I stay away from relationships and I work on the relationship I have with me. It's taking me awhile but I no once I reach that place I want to be I'll feel more confident and comfortable being in a relationship.
