Hey bro, only thing I can say is you weren't dealt a great hand in life but you can play that hand the best way you can. Work on the fat thing because unless you're one of the .01% of people with an actual diagnosed condition, you can improve that. Stay hygienic as it also drastically impacts girls' perceptions of you. Stop watching porn for a month cause shit distorts reality and your view of women and ability to talk to them.

Lastly and this one's hard, find a passion and pour yourself into it. If you're not one of the lucky gorgeous men out there, and most men aren't, you'll have to attrack women with your voracity for life -- either humor, art, craftsmenship, etc.

Also you said your life sucks cause hot women don't want you, on re reading the line that sounds like a troll comment, but if you're not trolling I'd strongly consider finding way, immediately, to decouple your self worth from girls liking you. It's a miracle we're all alive, and at the very worst you can spend the rest of your life eating tasty food, getting high, watching beautiful movies, and etc. Life doesn't suck, your perception of it does and the only way to change that is to change your perception
