When will this end?

I am in constant battle with my flesh. I replay past scenarios in my mind and I get extremely upset at all the times something unjust happened to me. However, I can feel the presence of the Holy Spirit telling me to stand still and on a spiritual level I am fully aware of how wrong it is and how we’re to love our enemies. I pray for this very thing every single day. I’m tired of being so resentful, I’m tired of my mind being full of these thoughts when I’m supposed to be praising God and focusing on more important stuff. This is very hard for me to share. I repent of this everyday and everyday I have these intrusive thoughts of anger, of things that people said to me, and about me and I feel like it is staining my testimony big time. Have you ever dealt with this? What’s YOUR testimony?
