Well the world isn't going to suddenly be like 'Woah! I didn't realize I was being too hard on you!'. If you have good friends they can help, but dealing with how you deal with life is something that friends usually cant help with.
Its like how a lot of people who are depressed just cant be reached. Half the time they CHOOSE to be there. That's cool n all but fuck if im gonna stick around and watch the show that never ends.
Just get yourself in the mindset to not let shit get you down. Sure stuff will still get you down, but your goals should be to:
1.) Always realize that there is more to learn.
2.) Make efforts to learn those things.
A LOT of people on the internet stop at the age of say 20 and go: I AM THE SMARTEST PERSON ALIVE MY LIFE EXPERIENCES ARE UNIQUE -- when in fact they are dumbasses that don't know shit about the world or themselves.
