YOU LIVE IN A FIRST WORLD COUNTRY, YOUR LIFE IS AWESOME!! TURN ON BBC NEWS SOME TIME AND TELL ME YOU DON'T LIVE LIKE A KING.
Seriously, depression rates shouldn't be some of the highest, and getting worse, in the USA. As North Americans, we are spoiled, ignorant fucks that live in relative luxury. That's why I keep up with the news, to remind myself how goddamn good I have it.
Have faith in the future. Start looking at college or university after high school, or taking a year off to ski. Whatever you do, don't smoke too much weed, because it makes the majority (not all, but most) of people unmotivated and they go nowhere fast. Don't stress, everything will work out, and you will hurdle and crazy shit along the way just fine.
As for girls, men aren't supposed to be hopeless romantics. As men we are supposed to suppress our mushy emotions. The best tip I can give you in general is confidence, confidence, confidence, confidence. Don't worry about true love until you are older and ready to get married, and then, it will work better to be romantic.
In general, as my friend once said, "stop thinking so much!!" Learn to enjoy the moment. Everyone should know that you can trick and convince yourself to being happy. It's called positive thinking. The next time you are about to complain or critisize, say something positive instead. Oh, and girls like that, too. Enthusiasm will get you to the moon and back.
Cheers
