Well, the alternative to fretting and feeling annoyed and hurt is NOT feeling any of those things. The choice is yours.
You have a life, and as you get older it might be best to concentrate on your own life and getting the most pleasure out of it you can.
As your children get older they need and rely on you less and less.
This is good as you brought them up to leave you and make their own lives. So you now have a choice, feel indignant and mull it over until you can't sleep or NOT.
Get out, get going and the next time they want you to drop everything, you won't be in, as you will be busy bungee jumping.
