I was really crazy for a few hours yesterday

I do not know how many more years before I will lose my sanity.
It was like a preview yesterday morning, I suddenly relive all those scary and paranoid feeling, it was all dark and very negative, it felt so real, I fear that bad things were going to happen to me but all that was not true in real life.
I don’t know what happen to the brain but substance abuse can really do that to my head. I was crazy for a few hours. I was capable of going crazy!
If I do not want to relive this dark and hellish feeling…I need to stay away from alcohol.
