Hello. I am going to try my best not to sound unfeeling or too harsh, but you cannot protect yourself from your mum dying, or from the emotional pain you will feel when she does. Anxiety’s “job” is to protect you from harm, but here it is out of balance because you cannot protect from it. What you can do is use it as a reminder to really enjoy every day with her and cherish her. So when those anxious thoughts present, rather than thinking “one day she will die”, think “how lucky I am she is here”. Easier said than done I know.
I also think perhaps you should do some work coming to terms with the truth that one day we will all die. And that is ok and right. As a PP said perhaps it would be helpful to try and work some things into your life that are just about you / not about your mum.
also you feel this way because you love her so much. Isn’t that wonderful!! To have had a loving mother and such an enduring close relationship. Yes, the absence of that one day will be painful but that’s the price we pay as humans for fulfilling relationships. I’m sure you wouldn’t have rather not had that relationship with your mum.
my mum died when I was 20 and I still miss her a lot, and feel it’s unfair sometimes…. But I think about how lucky I was to have those 20 years with such an incredible mother, and how much of her lives on in me and the ways she has shaped me as a person.
good luck op I know it’s hard but death is a part of life. The fact that joy, sorrow, love, grief, every single beautiful and painful thing in the world can all exist at the same time to me is part of the wonder of being alive!
oh and ps if you can’t tell I am a very very emotional person but I know I do deal with grief well, I think this is because I am fiercely protective of my right to my feelings. When one day your mum does die, yes, allow yourself to feel all those feelings, sit with the pain and let it be. But you don’t need to do that now. She is still here so sit with the good feelings, let them be and let yourself feel what you feel NOW, not what you’re worried about feeling (that’s abstract and unhelpful. Again it’s going to sound cold but if you really think about it you could even die first who knows?!)
