idk what to feel.

i’ve stopped talking to most of my friends and also my two best friends. i just drifted apart from them and idk why. one day i just developed a dislike for each of them and was like: ok, i dont need them anymore!
im not sure what to feel now. i should be feeling regret by now but somehow i dont. sure, i might feel small sitting by myself in the cafeteria or library but most of the time, i feel peaceful and happy alone. but i do feel bad for leaving my friends without giving them a reason why i chose to. honestly, i dont know myself. i guess it’s because i felt that i preferred doing things alone. maybe friends are a waste of time. im not sure but i definitely see an increase in my grades which is good!!
