I no longer have regrets.

I used to be consumed by regret, but slowly, over many years, I worked through them and came to the realization that what happened happened for a reason and taught me something.

Now I just try to be careful about whom I associate with, what my plans are, etc.

Living with regret was very painful. It is so much easier now.

I also find that depression, and especially early awakenings in depression, has regret as one of its symptoms.
