Honestly depressed

First off, screw anyone who says I'm "too young" to be worrying about a boyfriend/girlfriend right now (I'm Bisexual). I recently have broken up with my boyfriend of 9 months and it sucks. I kinda miss him but then again I'm glad I got out of the relationship. We've been broken up for about a month, and I have tried finding a new relationship, but no one seems to want to date me. I see couples everywhere I go and I want what they have...I wanna be happy for once in my life. It's so depressing with everything else going on right now and I want so much for someone to care for me and make me feel special...I see all these boys liking my bestfriend and no one seems to be interested in what I'm up to...I just really want that one person who isn't busy enough to text me atleast. Every relationship I've been in ended with them cheating on me and doing me so dirty...When all I do is give them love and other things...It breaks my heart to be that girl who no one wants. I'm always crying, I just want one person to make me smile all the time..It isn't fair. It seems like I'm always the one making people laugh and smile.
