Life'S Weird

I've always thought that at my age I would have some epic times with friends and everything. Now, I know a lot of people and only go out if I drink excessively amount of alcohol. If it wasn't for the alcohol I guess I would have no friends at all.
I'm really timid and anxious. I started taking lexapro 3 weeks ago and still havent seen any different whatsoever. I don't know where this is gonna end.
