Regrets?

[isis]

how can I approach this feeling/emotion of regret?

I accept it. I try not to dislike regretting things. When people say they have no regrets I seriously doubt they're being honest with themselves.

IMO, regretting is simply the mind displaying preferences. We can't help but have preferences. It's not necessarily a negative thing that we should strive to be rid of I don't think but I do try not to dwell on the things I regret.

There are many things I regret that I'll continue regretting as long as I'm able. I add things to my 'list of things I regret' pretty much daily.
