I need to loose weight for my confidence to be happy again, I gained a lot of baby weight, teen mom....?

I have a son I gained a lot of weight during pregnancy and need to loose as much as possible as quickly as possible, I am depressed, I can't deal with being overweight. But if I was hungry all day I wouldn't have energy to play with him to clean and be a happy perky barny talking mommy. I Just want to loosed weight, and dont care how healthy it is, I just want to be thin again, I need to be. I can't deal with this anymore, I can't look at my old pictures and be satisfied. I am fine that i had a son, I love him, it wasn't planned and I am doing it all alone I am 19, no friends, and very stressed but I keep a smile on my face except when I look in the mirror, or recent pictures. I can't do this anymore, please give me good advice. And adkins, going to the gym, weight watchers, isn't options, dont have much money either....
