My childhood is very similar. Alcoholic father who basically told me i didnt matter. he used to tell people in front of me. "this is our son steven who is very smart, this is my daughter colleen, we just hope she marrys a rich guy". I had a lot of anger for a LONG TIME.....

Therapy helped. posting here helped - your anger is very normal. I would tend to be the same way.

Take care. Hope to get to know you better.
