This is Kitt. You wentin to a rage and hurt someone.........I hope you mean verbally. OK so now what are your going to do about it to make things better.
Of course if you did something wrong then it feels like you owe them an apology and ask for forgiveness. You must remember people can forgive wrong doings but they may not be able to forget them.
Are you able to tell us what sent you into a rage?
If you can talk about it and get it out on the table then you should feel better. We are not here to judge you.
Take care my friend
