Trouble finding motivations to live?

I don't know whats been going on but ever since I have not been able to go to church I just have no desire to do anything. I used to love reading the bible or any kind of books but now I have no desire at all. I find it so hard to get up everyday and I wish I could be just not here. I dont want to see any of my friends and I constantly fight with my parents because I dont feel like doing my chores I just sit in the couch feeling depressed I eat a lot! and im putting on a lot of pounds. I used to believe I was pretty but now when people tell me how good I look I think they are just lying I dont want to go to the gym because I'm afraid of having to talk or see some of my friends I just simply dont want to see them. What should I do to get out of this depression I used to feel motivated because of church and God gave me strength now I'm powerless.
