DA37,

Self validation can be difficult and perhaps is common from those who has been abused. You mention that many people have validated your abuse. That inner critical voice that uses words like "you're too sensitive" sounds to me like an abuser's voice.

You are asking if you have been abused, and that alone might be a sign. Perhaps ask yourself what would need to happen in order for you to really validate yourself? What would it mean if you accepted this as truth, or if you decided it was forever false?
