Dear Leads (with a wave to Katy)~
Regrets are sometimes from decisions and actions we have taken, other times they are due to others or circumstances. It can be hard at times to know if you made a decision you now regret if in fact it was right or wrong. Rights ones can hurt as much as wrong -sometimes more.
I do not know your circumstances other than you are a 42 year old female by herself in hot weather. You have my sympathies about the weather, as a policeman I had to wear a suit and tie no matter what, it was highly unpleasant and now I've moved to a (relatively) cool state -a good move (sorry for the pun)
Regrets can inspire action, being by yourself can you take steps to start new friendships and social life? I remarried to my wife in middle age and we are still in love 20+ years later.
I'm only guessing and there is not much point to that -more likely to annoy if I keep trying. If you would like to say a little more that might help both of us and Katy (plus her robust hamster- sorry Katy).
It does not matter if it was the law, children, relationships, employment or physical injury - or anything, you can talk with us here as little or as much as you might like and we will have understanding and not judge. Instead we would try to help, there is a lot of experience here in the Forum
I hope to hear from you again
