i think guilt is very good. sometimes it works to stop myself from doing s/t i shouldnt (or not doing s/t i should), i remember what i felt like last time & imagine how guilty i’ll feel after doing it. & sometimes then its just not worth it.
i also seem 2 hav a fear of failure, but im not much of a perfectionist. i just dont try new things sometimes, & NEVER perform cuz im scared i will embarrass myself. its horrible.
