You might benefit from talking to somebody professional about this, but I'm also going to suggest an app that might at first make you feel quite anxious but I promise with use might make you deal with these thoughts more comfortably: https://www.wecroak.com/ https://www.wecroak.com/ It's self explanatory. I've used it every day for a few years now. It makes me feel far more centred, far less anxious, far more able to deal with the swells and dips of daily life. It has also made me face those fears about parents or myself becoming sick as an inevitability that can have a beauty to it. Ignoring it won't make it go away or any better, just all the more painful when it railroads into your life. Wish you well my friend, good luck with whatever you do, but if this approach feels overwhelming, definitely consider having a chat with somebody about it.
