Life is not pointless. I don't know what you believe, but I believe in a God that loves you and made you with a purpose - He loves you no matter what and He knows exactly what you're going through. When I found a relationship with God, life started getting better - slowly, maybe, but definitely better
So just enjoy the things in this world that are available to you. Enjoy it's beauty and in that, you free yourself up to enjoy the good things and cope with the bad because sometimes life is worth living just to see what happens next.
Or maybe this can help you :)
