Sometimes I get this same feeling as you do. There have been times where I just said forget about life. When I was a teenager I always wanted to just leave earth and hope that there was something better. It's up to you to try not let things bother you nor get in your way and try to make everything as postive as it can get. If you can have that mindframe I think a lot will work out for the best. I wish you the bestest luck and life and hope that things will get better.

It is always good to find someone to talk to about your problem. You will probably feel way much better to get things off your chest then just holding it all in when noone really know how you feel.
