There are things I regret. Not the things I have chosen, but the things that seem - unchosen. The way I am. The way I distance myself to the people I appreciate. They are few, and loved, yet I seemingly keep my distance.
I have a strong fatalistic streak and I would not be who I am today (a person I tend to like, against all common sense) without my past experience. I regret things that I could not influence. I regret being weak like an ancient old crone, sick, hurting.
But, no, mostly I regret being distanced, cold, when I don't feel cold. I have to learn to act another way. It will take time. I can only hope I am shown patience - a lot of it.
