I am really happy tonight as I've been freaking about my "switching off" moments which can last up to 10 minutes and finally found out why.
There is no apparent trigger apart from I'm not too happy with life at that time. Problem is I haven't got a "graduated" emotion switch. So I'm either smiling or crying, quiet or raging, well down or flying high. The end result is. I just switch off, aka zone out.
I don't collapse or anything dramatic. I just stand, sit, and it even happens when lying...
