cos life is better clean.
when i was using everything was tedium, or actually shit, punctuated by occassionally the drugs doing a 10th of what i wanted them to. i knew nothing could change apart from the for the worse if i kept using but i couldn't stop. i was heartbroken i'd never leave the country again, cos travelling is something i really love when i get the chance. i knew there was life out there but it wasn't for me.
even when i was a functioning heroin addict, which i was for over 5 years before i became a very not functioning crack addict, it was mostly shit. just that monkey on your back all the time. i couldn't stay out with my colleagues after work cos i'd start getting sick. the stress of not being able to score is a million times worse with a real job to go to. i'd flake out on my friends all the time cos i just wanted to stay at home using. or i'd come out super late and super fucked and people would be asking what was wrong with me behind my back. and i hated myself so much, i had everything, a good education, good job, decent friends, owned a house, holidayed abroad, and i hated myself cos i couldn't kick the gear. honestly not hating myself every day makes it worth it for me. the fact that i can actually enjoy my life is a bonus.
one other thing- when i got clean i had loads of stuff 'in the post' that i just hadn't dealt with cos i'd been using. 6 years of not dealing with anything cos i was smacked out my face all the time hit me back to back. i had to finally grieve for parted friends, realise a lot about my own behaviour, and process all the intensely traumatic things that happened to me while i was using, i was subjected to a lot of violence and sexual violence. i know you weren't using so long this time, but you almost certainly have some unprocessed shit that your brain is digging up now because you just didn't feel it when you were using. for me it felt relentless, and i was crying for weeks, but i finally got to the end. that's not to say i'm fine with all the stuff that hit me, just my brain has stopped clobbering me with it.
