I️ think I️ need help

I think I️ have a problem... I’ve always been a drinker but I️ started to slow down and now I️m starting to drink a lot/party all the time and I’ve been sleeping/messing around with a lot of different guys lately(8 different guys in just the last 2 weeks). I️ don’t know why I️ get drunk and mess around with random guys. I️ think I️ do it because at the time it makes me happy but right after I️m done I️ feel sad and empty again. My mom keeps telling me to stop and that she’s worried about me. I️ just don’t know how to stop when it’s the only thing that makes me semi happy at the moment. Ugghhh idk what to do? Thoughts? Anyone else deal with this?
