New problem creeping into my life

Good evening guys. Started having a new problem lately - I found this pub around the corner from me and it has a few really nice quiet corners to sit in and lately I've been going in there a bit. The problem is I'm going in there during the day, like at lunch time, and on a few occasions now I've drank too much and turned up at the office drunk. Yesterday, I went overboard. I have no friends, but in the pub I met a few guys who told me to come and sit with them and we drank heavily until I can't remember what happened. They left, and I vaguely remember sitting with this girl who also left, and then I woke up at home the next morning. This is really scary, because my dad was an alcoholic and I vowed never to drink. But, being depressed it seems like such a nice way to finally meet friends, something that I've been dying to have my whole life - just some companionship or even a girlfriend. Guys I'm so scared. This is not me.
