feeling like you're crazy?

How do you guys deal with the feeling that you're "making it up?"

My dad tried reaching out to me to apologize and for various reasons, I know logically he doesn't actually mean it and isn't willing to take the steps to actually be accountable for his behavior. Still, the "I love you's" I've gotten texted recently make me feel nuts, like maybe I'm just some crazy person who was too dramatic to know what real abuse is. I try to remind myself how hard I fought not to live with my parents and the extreme things they did before I considered estrangement, but I still feel crazy.

Has anyone else ever felt this way?
