im afraid im going into a slippery slope

i got divorced in 2015 after figuring out my wife cheated on me and fell into a massive depressive state, kids were taken, in and out of homelessness, out of a job. it was rough and i used alcohol and substances to cope. i drank/got drunk multiple times a day everyday for about all of 2018. ive recently gotten back on my feet and i got a job and apartment. some of my co worker buddies have asked me to go out with them for a drink after i passed out from “stress” (malnutrition) at work. i probably wont accept their invite anyways, im much too drained all of the time to go out for anything other than work, but im running around reddit asking for advice because im trying to piece my life back together and i dont wanna mess it up. would potentially going for drinks bring me back into a bad place?
