You know, you will always have time to end evrth up, but you will never have an opportunity to get ur life back...Imagine if you tried to kill urself, and you are dying and there are just a few last seconds of your life and you regret what u did- your kids that u never saw, grandkids, how you are getting married,how you getting a brilliant career...etc. It may be pretty sh...ty now, but give ur life a try!!!! U will die some day anyway, why not to wait and see what happens to you? it might be very ecxiting! U never know. And think about ur mommy, and daddy, ur friends, u cant do smth like this to them, right? and if we are talking even more deeply, it was not you who gave life to urself, so u have no right to stop it. Just try to cheer up urself, it is summer soon, full of sun, may be u should get some king of trip with ur friends on a car, like around Europe?
just forget the word 'MUST' and remember the word 'WANT' do smth that u want to do not must, that will cheer u up, remember that u are making ur life, so it can be just exactly how u want it, if u try a lot. and Good luck!
