i was recently diagnosed with ptsd along with obsessive compulsive disorder, binge eating disorder, and major depressive disorder. i'm 16 years old and have been struggling with my mental health for several years so i'm happy to finally get some help. i am taking fluvoxamine for my ocd.

my psychiatrist said the ptsd is from watching my grandpa die when i was either 10/11/12. it feels weird to think that that's where it stems from, especially considering it doesn't even bother me any more. i've long gotten over his death.

i also feel like my symptoms like hypervigilance, dissociation, jumpiness and panic attacks suggest something else. my triggers seem to not even have anything to do with death, usually i have panic attacks when people yell and if i think im going to get in trouble. i also seem to have this fixation on abuse even though i don't think that i've been abused, but i can't be sure since i have a large memory gap.

this is so much information, but in the end i just want to know:
is it possible to have ptsd from something that you don't care/think about any more?
does anyone else have a similar problem?
