Why i dont love....

The reason i dont love is because i feel that i would say no if i asked myself out i  feel like i am the worst possible choice on the face of this earth....

I just cannot think of a reason that people will love me enough to be commited in a relationship...  Even worse all my friends have put me as backup so it seems because if there is someone else they wont need me so i am just a person that will fill up someones time when they have no other option. I can only dream but i do not think anything will happen unless i have something to give back, when i go out with another girl i feel like hiding myself so i do not ruin their reputation or the way people look at them becase it just seem like i am a negative, just one big negative of a person...
