What to do if your a bony guy?

i'm very skinny acutally face it i'm bony scrawny guy and my face is really white (pale). No matter what i eat i NEVER gain weight. I have worked out but i see no results. Girls dont like me becasue of this i've been rejected so many times i lost count . I've actually had them say GOD you are sooooooo skinny. I dont even talk to girls anymore, because i'm ashamed of what i look like. I'm 24years old and i have never had a real girlfriend because of this. Everybody makes fun of me for being so skinny and i just look at myself like i'm nothing now. is there any hope for me i'm really tired of being alone :(
