Am I emotionally dumb?

Hello! I’m 17F, and I had an issue with my best friend this year that made me realize I might struggle with understanding how my words and actions affect other people and how I can’t understand other people’s feelings properly. I don’t always realize how something I say might make someone else feel, and I can get frustrated really easily. I also tend to want to solve conflicts incredibly quickly, but I’ve realized that this can sometimes put more pressure on the other person. Sometimes I don’t feel much emotion in the moment, and then later I feel extreme guilt. My best friend has also told me that I tend to shut down really quickly during conflicts. I’ve noticed something similar when I argue with my mom, although I actually cry a lot during arguments with her. I want to work on this because I don’t want it to negatively affect my other friendships. Has anyone dealt with something similar? If so, what helped you become better at recognizing other people’s feelings and handling conflict?
