As a therapist, lemme just say: almost every trauma survivor I've ever had has, at some point, said, "But I didn't have it as bad as some people," and then talked about how some types of trauma are worse. Even my most traumatised, most abused, most psychologically-injured clients say this.
The ones who were cheated on, abandoned and neglected say this. The ones who were in dangerous accidents/disasters say this. The ones who were horrifyingly sexually abused say this. The ones who were brutally beaten say this. The ones who were psychologically tortured for decades say this. What does that tell you? That one of the typical side-effects of trauma is to make you believe that you are unworthy of care.
Don't buy into it, because it's nonsense. It doesn't matter if someone else had it 'worse'. Every person who experiences a trauma deserves to get the attention and care they need to heal from it.
