I've had enough of life what now?

I can honestly say that I have had the same feelings. I know where you are because I have been there myself. You have got to get help. Please, do not do anything rash. Are you a christian? Perhaps talking to a man of the cloth will help you. I know that Jesus Christ has an unconditional love for you and I urge you to seek Him out. Remember this, the only way to get better is to keep breathing in and out. I will pray for you.
