Good advice Alan Brady's hair and Catsrule!
IDK if you are religious? I find going to Church to be very peaceful, and puts me in a good state of mind! I wis I had the time to go more! But my suggestion is if you are religious, try going to Church and maybe joining in some parish activities. I think you might be able to meet a nice girl that way!
Good luck to you.
Sorry you are feeling so down!
