scary,
I'm sorry you had to experience this with your mom. I understand how that can hurt deeply. My dad passed a few weeks ago. His anger (at times rage) and intentional indifference (it's called leveling) toward me all of my life - since I was a teenager - are the only memories I have from him. My mom told me shortly before she passed about 15 years ago that my dad had been jealous of me forever. I was stunned, but it finally made a lot of things make sense.
At least you have good memories of a loving mom that you can help you through this period. Rely on those memories.
