I get that way emotionally. I get into a fear cycle of all the what if's of the future and when I am like that I need to isolate to keep from feeling more overwhelmed and tearing off anybody's head that happens to be in the vicinity. That was one reason I fell into drugs so easily..... it numbed me emotionally to fear and anxiety. It wasn't about other people it was about panic attacks. Lord I've asked this before but what did they do 200 years ago when they hurt physically and emotionally? Hit the booze? Chew on some sasafras bark? Beat the dog? Hopefully your day tomorrow will be a better day. A healing hug for you.
