Interesting that you are an adult and she is still strict towards you. It's probably too late but try to turn the anger into pleasure. I had two aunts. One I thought of as the nice aunt and one I thought of as the mean aunt because she was super strict with me just like her sister, my mother. I originally thought I liked spending time with my nice aunt more. Then I started getting bored with her and realized I got a tingling sensation when my mean aunt picked me up. Every time she criticized me or snapped out an order or was unpleasant towards me I got an emotional charge out of it. On one hand I hated it and it hurt my feelings and pride but on the other hand I loved her and had to admit that deep down inside she was my favorite Aunt.
