Hello and welcome! I think that one such incident could certainly affect a child negatively. Your mother certainly did and said things that were very scary and hurtful--and then the fact that you had no one to talk to about it kept those bad feelings inside you, and they came out in the ways they did.

I assume you haven't been in therapy to even tell a therapist about it. I strongly encourage you to do so. I think you will find it very helpful. I know therapy has helped me to deal with mistreatment by a mentally-ill mother.
