I've Got It All, But I'm Still Sad

I have a very loving girlfriend, a good job, and a family I can reach out to. My family is kinda meh, but they're good people. My girlfriend is literally the best. and my job sucks, but it pays pretty good. Despite all of this, I'm an alcoholic and idk what to do about it. When I was younger I drank to forget, but now I just drink. r/quitalcohol might be a better place to post this idk. i have considered switching to a job thats less bad for my health, but I would take a serious pay cut. i dont know if i could live on a wage in a career that would suck less. but at the end of the day its all work. i dont know what to do. i think i need rehab, but it seems inaccessible. I want to quit, but dont. my life goes on either way. i have hobbies like playing guitar, learning japanese, and programming. i go for walks, bike rides and runs, and i have faith, but nothing seems to change how i feel. a lot of people get hungup on the news, life drama and the sort, but as far as im concerned- tomorrow im going to wake up at 6am and go to work. thats it. sleep, work, die. i guess. idk how to get past the feeling. i save and invest, but for what. a maybe? i might have wealth one day. its not guarenteed. neither is my happieness. i dont know.

tl;dr pretty good life, work sucks, and life has lost most meaning. despite a seemingly good working class life.
