KrazyKat, I am not inclined to just accept what someone tells me, regardless. That said, my psychologist tested me and had me tell her about myself. She said I was ADHD and I had entitlement issues. It felt right, there was nothing that I felt any need to argue about. Had not considered ‘entitlement’, but it fits, and she has me in some Behavior Therapy to unlearn my bad habits as it were.
The site here has tests you can take as does Dr. Barkley’s Taking Charge of ADHD. Do the tests, see what you think.
Beating yourself up is unproductive or counter-productive .. or something .. I have no idea where i was going with that .. good luck
