I have a stuffed tiger my mom nicknamed Mikey...because my best friend(of 10 years), Michael, gave it to me in 3rd grade. I'm always more than happy to curl up with it and go to sleep when I'm upset :D
Just eat. Eat healthy food, drink lots of water, and exercise regularly. You'll be both healthy and in shape after a while :D Don't starve yourself...it's the wrong way to go about things...
Actually most people that aren't attractive or don't have much going for them...or they feel like they don't...start putting out at a young age so guys will be interested...even if it's for the wrong reasons. There's that option or you could try you're best to look the way you want to look, be happy with yourself, and wait for a decent guy to come and find that your beautiful :D I'd really suggest the second option...O.o
People tend to not understand that when you hurt someone...if you ever actually cared about the person(which u most likely did since you dated) it's going to hurt like hell when you hurt them...or if you have any heart at all. I'm a girl and I've never had my heart broken...but I've broke at least two hearts out of the four guys I have dated...probably more...and it was intentional...and it hurt me more than it hurt them o.O
