Anxiety and aggressive. It get resolved?

A few months back I got to know about something which affected my mental state and me deeply. Now I'm unable to get out of that situation, I'm getting aggressive day by day I never used to behave like this, but nowadays I'm unable to control my anger and unable to cope with the situation. I often choose violence to control my anger or show my emotions. I feel extremely guilty for it as it hurts the other person. I want to forgive that person or leave but I'm unable to do both. It's affecting both people's mental state. I feel extreme anxiety, continuously overthink about the situations, imagining things and it keeps getting worse and sometimes I feel like I am unable to breathe too Do I need therapy? Can it get resolved?
