I don't usually start threads asking for advice, but I would welcome some now.
My Mum and I are very close. We live over 300 miles apart, so we try to see each other several times a year and keep in touch by phone and email, etc. She's married to a lovely man and our families are blended, but it's really me and my DH who are closest to them.
Both are in their 70s with active lives, but both now have heart problems and the other health issues that can come with getting older.
The problem is I find I can't stop worrying about my Mum. I worry about losing her and I worry about her if she loses my Step-Dad. I'm being confronted by her mortality. I'm not usually an anxious person and I know in my head that I shouldn't worry about something that hasn't happened or I can't control. I know I should count my blessings that I still have her, but I still worry.
Does anyone have any advice on how to stop this worrying please?

Easier said than done of course, but try to shut that worry up in a little box in your brain and not open it until you have to. You have a lovely mum with a happy life, and a great loving relationship with her, and with luck this will be the case for many, many years to come. Just keep in constant touch as you are doing, leave her in no doubt that you love her, and give her the biggest hug every time you leave her, as that will be the moment you remember when the inevitable happens. I ran back from the car to give my mum an extra cuddle the last time I visited, and that was a comfort to me later.
She worries about me and my health too and we both have to winkle the whole story out of each other sometimes. We're both guilty of not telling the other about something that's going on health wise (I'm doing it at the moment). I suspect my own health concerns have been partly responsible for my starting to worry about losing my family. It's just not like me not to reason or rationalise worrying about something I can't do anything about. I'm no longer a religious person, but I even go to church with her and thank God for keeping her safe - the rest of my family too.
