I need major help, I feel so depressed?

I agree with the other response up that you should change your clothing. I think getting proper fitting clothing would really help your self image. Wearing stuff that is too big with make you feel even smaller. Being a girl, I know that it's not only a physical attraction that draws girls toward guys, it's personality too. Many girls like nice guys and especially ones with confidence. If you want to gain more weight you could work out and gain muscle weight (personally I like skinny guys and I know a lot of girls that do) but I know that if you liked yourself more and acted like it, you'd draw in more people. You have to open up to people if you want them to be close and have a connection with you. If none of that helps you out maybe you should talk to a councilor but know that there is nothing wrong with it. Councilors are there to help not make you feel bad about needing one, if people were honest a lot of them would be seeing councilors anyway. If you want an organization, maybe you should volunteer at a place like Hospice as it could help you see that many people have problems and if they can see the brighter side it could help you. Good luck with your journey.
