Don't ever do it. It's not worth it.

The good side of having been on the bad side of things is you know how low you can go, and you've been there before and you're still here. You know you can make it through because you've done it before. You've faced the darkness. It's a strength. Take pride in that. It's not something everyone can say for themselves. You've been through hell, and you maybe live there full time, but you've been tested and you've survived this long, you can make it through.
