I suppose you could say I've dealt with some other issues, mainly in my teens. I dealt with depression (never formally diagnosed) due to some other issues that were happening at the time and issues with alcohol at a young age (blacking out, drinking until passing out etc).
Nowadays I drink socially and dabble in recreational drug use (I am in my twenties btw), but I am quite controlled with that kind of use. I have a professional job (ironically I'm a mental health worker), so I am conscious to not mess that up.
There's a bit there, however I have a supportive friendship group, family etc. But they obviously have no idea about any of this. I've had difficulties holding down a relationship longer than a few months also.
