actual trigger warning

yeah I'm just writing a few words so what I say doesn't pop up and trigger someone. I'd hate for that to happen. so anyway, anyone who has been raped, molested, or sexually abused have flashbacks randomly when you picture something you'd like? or something your partner says/does trigger you? because I've had it happen to me a few times. and currently it's happening. I'm trying hard not to have a panic attack. any advice to prevent things like this from happening again?
