I was just thinking about my mental health, the reason I stopped drinking and cant take any drugs is all they do is give me a rush of adrenaline or whatever and when that feelings gone I feel worse than before I even took it.
When I used to feel normal (which was when I had low self esteem but enjoyed life) I had a permanent adrenaline feeling though not to extremes so I could go to corner shop and feel a little ticklish (so thats why I assume adrenaline) and very minor giggles as in I would smile and every now and again would make a sound like "heh" even when playing a video game my heart would beat faster and my feet would start tapping faster and faster.
Sometimes I was so excited I would literally just make strange sounds like "yay" "woo" as my body was so tickish/tingly.
Though that may be more due to the fact I am mildly autistic.
In recent years I have not felt that once, well I have felt some of those symptoms but not the whole picture.
