So perhaps you lose the present with the past or daydream about the future. No matter the situation, for me every moment of life is wonderful, being alone is okay because it is not synonymous with loneliness (in other aspects, loneliness also appears as happiness lost in the crowd)

I have quite a lot of things I can do while I'm alone like reading books, listening to music, watching movies, working, drawing, meditating,... there are really a lot of things I can do when I'm alone. don't bother anyone. Maybe I always feel complete with this life, even when facing challenges in life, I want to solve them myself.
