Why do I start crying when I get really angry ?

I just noticed when I get really really angry, I start crying like crazy, what’s too this ? Does it mean I can’t handle my emotions well ?

Like today I got into an arguement with my boyfriend, and I felt in so much pain, and anger – I started crying because I was so frustrated and didn’t know what to do about it.

I cry because I feel the anger is too intense, and I don’t know how to release it or what to do.

Does anyone know why this happens ?
