I Was Not Allowed to Feel Or Express Anger Growing Up

After a long long time, i expressed my anger by talking it out loud. Don't even remember the last time i did that. It feels good, don't know what made me talk angrily, but i just couldn't keep those thoughts inside me and writing wasn't enough. This is a huge experience coz i was never allowed to express anger even as a kid. Even after i started to learn more about feelings, i had a hard time expressing anger. I used to watch some people get angry for nothing and I could never do that. I didn't know how. I used to write to vent about things that made me angry, but talking and expressing it out loud - never.
I feel liberated from all the repressed anger.. coz expressing anger isn't 'bad' or 'wrong', expressing it only means that something bothered me or offended me. I just hope i don't repress my anger again, and that i'm able to express it. I think i repress it coz i'm always scared that it would hurt the other person. coz i've been hurt the most by my mom's anger. I know how the words hurt and rattle inside. So i learnt to keep my mouth shut and never express it. But sometimes it's necessary to express anger, or else it starts eating you up.
