Same here. It comes back right after I attend a social event or do something fun. That high that I get when I'm around people is there but when I'm alone, I'm scared of the loneliness. Is it perhaps a lack of self - love or compassion for ourselves that we are uncomfortable being alone? At least, that's how I feel. I think I lack self - compassion that sometimes I fear being by myself. And sometimes I can't find anything to keep me busy or stay focused.
