>>13596875Sure, if you don't know anyone, you've got to go where the people are until you make some connections. You could volunteer or join an activity club, but bars and nightclubs are the easiest.
Sometimes you go and sit around awkwardly with your drink, and nothing good happens, but often you'll manage to strike up a conversation with some interesting people, and eventually you'll hit it off with people and get invited to a party or trade contact information and have someone to go out with.
Don't focus on picking up girls. Aim to make friends. Girls are going to be wary of a guy who doesn't come with friends, because maybe you're such a rotten person that nobody who gets to know you wants to be your friend, or maybe you go to the other side of town, away from the people you know, so you can cheat on your girl and probably not get caught.
Make friends, hang out with them where you can make more friends, your friends will introduce you to girls. Rebuilding a social life after getting isolated is a slow, discouraging process. Just tough it out, expect it to take months, and remember that almost everyone in a bar is there because they're hoping to meet new people.
