If suicide is not the way out what is? (From a teenagers perspective )
Living life to the fullest! 1-800-273-8255 call for someone to talk to.
Realizing that whatever your problem is, it is temporary. Many if not most teenagers feel alone, scared and like they don't really fit in at some point. You just need to be selective with your friends and hang with those that support you and your dreams. And don't listen to the bullies and those that try to put you down. By the time you are ouf your teens you will realize that they never really mattered.
Never give up. Did i give up on my drug problem no. Did united states give up during ww2 no. Dont let others put u down fight back
The way out? Patience. Endurance. Courage. Determination.
From ANYBODY's point of view, suicide is the action of a loser. It's the total waste of a life.
This sounds promising:
