God gave me the gift of music, but cursed me by making me depressed

I can play the guitar really really well for my age. (now I kniw that's not saying much about my personality but oh well) I can tell by the way people react to my music, but I honestly don't care. I can tell by my ear too. I can just play any song on guitar without ever hearing it. I know music theory. And I can do it all well. But I'm depressed. I can't do anything. I just sit around. I'm skinny. Insecure. I don't talk to anyone. I'm socially awkward. I'm depressed about my appearance. God gave me a talent for singing, playing guitar, and music. But he cursed me with depression and uglyness. Honestly I feel like this is more of a curse than anything. I'm a fat, depressed loser, But I can shred, sing, and play guitar. Why? I'm never going to be able to make the most out of it. It's useless. I will eventually end up alone, and I will end up quitting my dream job to play music.
