It's a form of depression, in a way, Endo-Geneous or something like that. Basically it means it comes from inside of the body for no reason or many reasons. It's basically everything taht has built up over time, all the things we've gona through, seen, done, heard, etc. It builds up in you and makes you likes this. It also might be another form of depression, look up on good the different types of depression, find which you have the closest symptoms to, then go to a doctor and see if they can do anything. Mayne find a psychiatrist or counselor that you can talk to about this and get a second opinion.
What drug did you OD on?
My brother OD'd on the highest grade of pprescription Zhanex not long ago and was clinically dead for over 10 minutes, so maybe i can give you some advice on how to get over it. I was the one that found him and kept him alive before i called a nurse friend of mine and eventually 911. One of the worst days of my life, me and my brother have always been close.
Trust me i know how you feel :hug:
