I've felt the same way for over 15 years, no solution in sight. I've tried the meds for many years, I've tried therapy, cognitive behavioural therapy and many other things and nothing has worked. I've also started to feel less interested in things I thought I was interested in. The only thing really keeping me alive and fighting is my girlfriend and my family, which I have pretty poor contact with if I'm honest, but…
I thought about exactly this today. If my family or a gf need something, I just do it. Call it, buy it, work it, solve it. No procrastination, no psychological problems. But when I’m finally alone, nothing drives me at all . It’s sad to think that I must go and find/make someone to live for, just to able to live. Makes me think that people who talk about kids are just those whom it hit much earlier.
Maybe you need find some place to volunteer? help your community? or do any kind of meaningful work?
