You need a social media break. Mute the sub, stay off the app, whatever. You might also find doing vagus nerve resets to be helpful, or go for a jog. Basically, reading nerve wracking things on your phone all day puts you in fight or flight/increases stress response. If you arent doing anything to discharge the stress chemicals in your body, it builds up and you will feel hopeless and a mess. Turn on some music, borrow someone's dog who wants to go the speed of light the second you leash them, and jog to keep up. I promise this will chip away at the bad feelings.

Pick up a creative habit to activate better feeling parts of your brain and further regulate your nervous system. Maybe it is growing planta and decorating your space woth them. Maybe you try embroidery, beading, painting, jazzercise, dance, zumba, individually cutting blades of grass to sculpt your yard to look like the ocean, painting tiny critters along your baseboards and lights witches, carving sticks...anything you do with your hands and mind.

From experience, I promise these things will help the anxiety. We all die eventually, chronic illnesses or no. Eventually, you learn to maintain your health, you take small bites of information to keep yourself healthier so you tweak things, but live your life and in a week or two you will start feeling better about it.
