I'm sorry you are feeling this way, it must be so lousy. :/
First, I completely get the feeling of not being cared about, attractive, ect. Everyone has felt like that at one point or another!
My best advice would be to change your attitude about things. It may be hard to do this when you feel so crummy about yourself, but you should approach people. Talk to people. Make friends! (Not as easy as it sounds, but if you get out there and start trying it will come!)
I am sure that there is someone out there that is right for you, and you will never find that girl if you dont go looking.
"Take chances, make mistakes."

As for loneliness, there are things to do to get out of the house besides being with a girl.
Could you get a job? volunteer? Maybe taking your mind off of things will help give you a fresh start.

Good luck, I hope this helped in some way. You wont feel like this forever, this is just right now and you can do something about it.
