I swear I've seen you on another forum asking this... but regardless...

If I'm honest, you simply look very average.. like as in ordinary.. the sorta girl you see walking past you in the shop you and don't take any notice kinda thing. You're not ugly, but I think physically you're plain? I know it's not complimentary to say that but like perhaps you could try wearing make-up tastefully and get a new hairstyle. No need to clown yourself up, but yeah. I realise this is going to sound pretty unpolitically correct, but yes looks do matter in a relationship, it's what establishes attraction, although how important they actually are varies from person to person, sometimes it's minimal sometimes it's roughly half the package. Personality is what catches and keeps the heart, but regardless, your looks aren't a deal breaker and you can definitely improve upon them if you want.

I'd be very careful though, you sound emotionally vulnerable and there are idiots out there who would take advantage of this, and on the flipside "looking for a boyfriend" won't help you find someone suitable, most people can smell desperation and people deliberately searching for relationships about 100 miles off. So you need to work on your self-esteem, physically improving your appearance will help you feel better about yourself and tackling any mental/emotional health issues you have and just build up friends through networking in life, or you could try internet dating (like Plenty of Fish or OKCupid) when you're ready, although you have to be careful of the creeps and fakers out there, but internet relationships do work well for some people, since everything can be done at your own pace and whatnot. Whatever you do, please don't listen to the usual "get down the bar and pick up a man" or "just go clubbing" style advice you hear from some people out there.. men and women are generally different in this regards, a man will often get a confidence boost from a one night stand or whatever, but women will feel crappy after them since the emotional void is still there.
