Am sorry that you are feeling like this
i struggling everyday with triggers from the smallest things to really big things
with me its got to the point where i cant watch films that are aged 15 or 18 rated
i can watch 12a but i have to be careful as dark knight was a 12a and one of the characters face gets burnt and it was graphic i had to walk out the film house because of it
I have started to watch anime its dont trigger me but i have to be careful just in case

you cant help things trigger you its how you deal with that trigger
i not sure if you self injure etc do you like doing art? if you do try doing some
or try writing poems or stories anything that keep you busy and your mind occupied
