I am sure that in old age we will all regret what we didn’t do versus what we did.

I like to think that at any given time we all make the best decisions that we can, at that time. Regrets are an awful thing to have (I know this from experience) and there is certainly no magic pill to make them go away. If, however, we all know we are doing the best we can at any given time, the regrets are minimised.

It's good to see that you took the time for yourself that you needed. So many people don't. I've even told my own children (old enough to care for themselves) that they are on their own for a weekend because if I don't take some time to care for myself, I will not be able to care for them when they need it. It's a balance.

I am beautiful either way

Yes you are. Everyone needs to tell themselves this every day.
