Tins - get an electric opener. No coordination or grip strength required to push a non ring pull can into it and press the handle down.
Light bulbs - switch to screw fittings. No pushing up and twisting like you do with bayonet bulbs.
Sewing and knitting - bar possibly putting a button on (and for that you can get a little tag machine like is used to attach labels to clothes in the shops), it's easy enough to get by with a combination of using iron on wundaweb tape and taking things to an alteration tailor or a dry cleaner that offers repairs.
Blow up balloons - good. They're environmentally awful and the sound of them popping is enough to cause physical pain.
DIY. If you can't/don't have the coordination/strength or the spatial awareness, it's probably for the best that you don't. Keep your local handyman and decorators in business when your DH doesn't want or isn't able to do something.
Cook very well - you could probably get better with experience, but if you can do basic things like heat up something from a tin and put it on toast, cook pasta and add a sauce from a jar, open a bag of salad and put it on a plate, microwave potatoes or anything that has instructions, that kind of thing, you aren't going to starve anytime soon.
Cleaning - you could probably improve if you started with small habits that reduce the build up, such as always putting packaging into the bin as you're cooking. But if not, you could employ a cleaner. If you get PIP, it's a perfectly reasonable use of some of the money.
It might be better for your state of mind to look at things you actually need done and how you can either do them or get around them, whether it's by planning the need away (such as when you buy tins with ring pulls) or by outsourcing (like a handyman or cleaner), though. And to consider things that you can do/are good at, because there is likely to be something.
