Resentment about a project

I took on a project that from the start I didn’t want to take on.

The main thought that led me to take it on was that R, the person whose idea to do the project it was, didn’t know how to do it and I had more of the skills than he did. I guess the F was obligated. The As were that I took the project over from him and I built an app. And then the R I dunno.

Now I am feeling resentful because I have run into some issues with completing the project and I am thinking I never wanted to take on this project from the start. My As are that I am ruminating, regretting the past, and the R is that I don’t ever complete it in this model.

Can you coach me on this please?
