Do you ever try to remember the day that you spent with your friends after you've said goodbye and stuff? Since our brains are biased for bad memories, doing this will help the chance of these memories being registered on long term memory. And as you go through the things that happened, have you noticed the very cringy way you acted/done sth? And remember the way your friends acted so that you wouldn't think what u did was uncomfortable in any way? Then say to yourself ' why do i even speak or do anything?'. Just me?
