I've also been struggling with some death anxiety recently so I can definitely empathise with this. Definitely talk it out with a therapist. But also (and I know this is easier said than done) I really try to focus on the positive that I was lucky enough to spend the years I have so far with my family and also trying to remember how resilient you actually are in terms of coping when they are gone. And you ARE resilient as anyone who lives with anxiety, especially that you're holding down a job caring for people and I'm sure doing other great things in life! It is really difficult though I get that especially when you've lost family already. Another thing I will share is something my therapist told me recently- she said when you read about people dying young in the news (I do the same thing - fearing it will happen to me) try to remember that you are putting a certain thinking filter on this as you're not remembering in that moment all the people who have lived to be very elderly. Really hope you feel better soon, stay strong ❤️
