Pent Up Anger Being Released

For so many years, I never showed anger. I thought it was a good thing. I never let things get to me. If something did make me mad, I made sure to hide it inside.

But now everything's coming out. Every little tiny thing makes me mad, and I am snapping so much. My cat just jumped on my desk and I pet his ear, but then he meowed and ran away and I said "Well I don't like you either!"

I was really taken aback by this. I did it without thinking. It's like subconscious took over for a second. I didn't even know that I harbored those types of feelings. He's done nothing wrong to make me dislike him, so why would I say that?

It's just not normal for me, but it's happening so much lately. Can you help me with this? What do I do?

I don't know how to manage my anger either. I also used to pride myself on being collected and not letting myself explode. I think my brain chemistry changed though because even when I'm not angry I feel like I'm on the verge of being upset. Maybe it's just that I feel like I'm on pins and needles but I question whether my thoughts are not valid because I may be mentally unstable. I do have many stressors. GL
