 Not attractive enough, I don't know what to do.

I don't like myself, I never had a girlfriend. I don't like my face, my body, my jaw, my hair, my eyes. I'm so tired of everything.I think because of my mental problems in high school my looks got worse. I think that the other guys are better than me, that no one will love me.

And if someone falls in love with me, then they will leave me, cheat on me.

I would like to heal my mental trauma and then my looks would begin to change for the better.

Why am I so obsessed with looks? I've been told that I'm ugly

I will accept any support.  
Thanks.
