why doesn't anybody want me

I know I know I will find love when I least expect it. But I can't help it. I want it. I crave to be loved by a guy so badly. I've never had a boyfriend before. 16 and a half and I'm single still. I have found about 5 amazing guys in the past year and they all seem not interested to take it further or it turns out they have a girlfriend. Oh and one guy only wanted sex (:   I just want to find love already. I'm lonely. Not with friends or family but I'm lonely for a partner.  😭 I feel like no body wants me because of my weight. I know it is it always has been.
