So the guy you met, could he be a friend rather than a boyfriend? There could be lots of reasons why he doesn't want a relationship but he might value a friendship.

Your best friend, try to clear the air with her, agree to differ about her online fella. She probably lashed out at you and said stuff she regrets. If you can't clear the air then maybe you're right and your friendship has run its course, sometimes things work out like that.

You might not be able to do much about how pretty you are, but you can work on making the most of your assets (nice clothes, nice hair, a little makeup) and hard as it is most people can lose weight if they work at it. Don't give up on yourself just because you don't match up to the artificial conventions portrayed in the media.

Not being able to cut, probably means you have a nice, soft, supple skin and maybe has a little to do with cushioning from sub-cutaneous fat. That tells me your skin will age well and you won't be troubled by wrinkles (not much of a consolation right now, I know). Cutting is a horrible and addictive behaviour you really are better off not being able to do it, you are certainly not a failure because of not suceeding at cutting.

You recognise that you are not a failure at work, what is it you do? Concentrate on your ambitions for work, it is a much better distraction than cutting.
