i have a good life and i still feel like shit

i just need a quick vent, idk how this works tho, so i have a good life, great even, i have a good relationship with my parents and healthy friendships, i haven’t lost anyone in a way that scarred me, i haven’t gone through anything in comparison to my friends. my friends have gone through a lot, they’ve either been bullied, neglected, abused, or just gone through a hard situation. they struggle with things i do, specially sh, self hatred and suicidal thoughts, but i don’t have a REASON TO BE, my friends do. i just wish something terrible would happen to me just so i can have an excuse to feel the way i do, but i don’t, so i just end up feeling guilty because i don't deserve to feel the way i do. my friends are supporting, and they keep on telling me that it is okay because it’s hereditary or something, they don’t judge me. but it still feels like something is missing.
idk of anyone else feels like this…
