WHAT AM I SUPPOSED TO DO NOW !!?

Really, your life doesn't sound all that bad. You have a life, a computer, and a horse. Young women your age can be fickle and sometimes it's really hard to find a place for yourself in university. It took me a couple of years to find consistent friends. You're getting caught up in little problems, and they're tying you down like the Lilliputians tied down Gulliver. Quit thinking with your ovaries and study more and more productively. You have time after college to find a relationship. You shouldn't have any trouble finding casual sex partners for the occasional release, however. Good luck.
