I'm the type of person that laughs when I get physically hurt.
Best advice I can give her would be the same thing Nic and everyone else said.
If the relationship didn't work then needs weren't met and you weren't met for each other. Just calm down and stay with your friends.
Love is dead and hopeless.
Forget about whoever you thought cared about you. Matter of the fact is that they didn't and in a years time all will be forgotten.
Once someone dumps you it will never be the same. That person is not who you fell in love with. To me, my ex is dead and long gone.
I found out they got engaged two months after she moved out, two months
"I don't seek out guys. They seek me, and then they hurt me."
So seek out someone that won't hurt you.
When I was younger people always told me "nah you're too young to worry about this stuff" and I never understood why. Now that I'm 21 (which to some is still too young to worry ) I really see that argument. You won't understand it either but you really are too young to worry about relationships.
Probably the only viable advice I have for you is "force your boyfriends to wear condoms"
