Depends on what you consider peace. Nobody truly knows what lies beyond. How can you know that peace is when theres NOTHING. absloute nothing is a hard concept I know. A good analogy is Trying to look through the back of your head you cant see back there in the slightest there ain't shit. not black, not light there just ain't shit... Y kno what I'm not even going to bother with that speech, or anything else for that matter. Just know you're taking the fools way out you're in Last Stand and holding X. My philosophy is DONT GIVE A SHIT. Stress is stress is stress. A pain in the dick. But when you stop giving a shit theres Mountains less of it.
Also you could just have a easy fix chemical imbalance. I was depressed for a few months before i really started working out and taking supplements. turns out I had deficiency's in a few minerals that your brain needs. try some supplements, that helped me. You'd be surprised at the results they get from clinical studies.
Do this for me. Just try taking mineral supplements. If you dont notice a difference in the way you feel then go right ahead I wont stop you.
