if you are this unhappy with your weight why dont you try more activities. Just doing 10 min walk everyday can make a difference. Anyhow loooks is not everything to everybody .. personality,job, success are highly rated too =D
Anyhow, depression is such a horrible illness. I have experienced it and it came to a stage i didnt want to go out anymore. However, there is light at the end of the tunnel. Surround yourself with people you care about and love. you seem nice just have confidence in the true person you are and there is somebody out there for you. Just keep looking ^^.
p.s. it seems we are similar so msg me anytime x

just get out there...and seriously dont be depressed about not having a girlfriend..i had flings in high school but they were never official boyfriends..i didn't become involved with my first serious boyfriend until i was 19...i dont feel like i missed out on anything...live up your single life boy! get out there, have some fun and maybe along the way you'll meet you a sweet girl! But you cant just sit around and expect her to just miraculously show up haha...and as someone else said, if you're unhappy about your weight(i think all of us have a few things we'd like to work on) then get up and do somethin about it! Go to the gym! talk about meeting girls..thats the right place! working out gives you natural endophines as well, you'll feel better about yourself and you'll be happier..its really good for you...just get out there
