So, we have been best friends for years and years (we're 17) and we used to hangout every weekend

Then back in June 2018, i got a GF, and we all know how that goes. I kinda left him. Only talked at school, and struggled to hold a relationship because i was so hyperfocused on my Mrs

We broke up in December 2019

I think this caused him mental health issues. Hes never been the most outgoing person and struggled to make buddies. now hes really bad mentally and i think its because of me, and i just figured out he tried to commit

Im not supposed to know but im not stupid, and im very aware of why his details of absense would be hidden, having dealt with mental illness myself

What the fuck do i do. I lost him, i feel. Im just so busy i forget to message people

But whenever i invite him to things or ask him to plays ps4 with me he says hes busy, but we know he just doesnt wanna be a burden and/or is way too introverted

Im a mess, im fucked, this is fucked

I dont know where im going with this, but any advice would be nice please
