Dude posting on message boards about how you're a depressed person who is not like by anyone and who cannot find a girlfriend isn't going to get you anywhere. People may read your posts and comment on them but they have no real idea of who you are and could possibly care less. If you want to change your life, you also gotta work on it. Make plans! Be realistic.
Can't find a girlfriend? Well, if you never talk to girls you're never gonna find one. Dont' expect God to send you this beautifully formed, attractive girl form heaven just because you're a christian. Organize a plan, pick a girl you like, consider her pros and cons, is she an spiritua person? Can you have a cup of cofee together while holding a meaninful conversation? if she too look looking for you? too short, too tall, too fat,too matelialistic, you know what I mean? Be smart. Think of an ocasion when you're gonna have the time and the space to approach her and simply be yourself with a smile.
Can't get real friends? Then look for people who are compatible to you, being a Christian isn't enough, we also have our own personalities. If you're a reader, go to the library, of you like sports, join a team, if you like missions, join a mission.
Be optimistic, keep your head up, risk yourself even when the nerves are about to burst your belly. God did not give his children an spirit of cowardness! Show it!
