Can I be angry at my parents after they shamed me about my finances?
Well, how do you feel when your parents get up in your business?
I get this mad feeling from daily encounters with my parents as a result of my strict upbringing.
People should not shame you about anything, especially your parents.  It's understandable that you would be upset with your parents for shaming you, and if they really loved you they would be trying to help you instead of putting you down.
It's okay, I'll use this to get some sympathy from my friends.
You have always been vocal and strong-minded. Why not just stand up to your parents and let them know you are old enough to make your own decisions? It might stop them from shaming you going forwards.
