Is it possible to block out bad childhood memories ?

It’s it psychologically possible to block out a bad memory of something traumatic ? ...for some reason I’ve always been triggered by hearing rape stories and stuff like that makes me have great anxiety to the point of panic attacks sometimes ...but idk why ?! I can’t seem to remember anything traumatic happening when I was younger. Can this be a “normal” reaction to such an awful topic ?! Or should I seek help to remember a “blocked out memory”😔😫🤨🤔🤔🤔
