Tips wanted for daily activities with weak or painful hands, wrists

I was recently diagnosed with lupus, multiple connective tissue disorder and also fibromyalgia. IT seems to affect my hands and my wrists terribly causing weakness and pain and so I'm finding it very difficult to do the things that you would normally do on a regular day.

Things like opening a gallon of milk or buttoning your pants or just daily hygiene becomes difficult because you can't open toothpaste or you can't open shampoo so it's very frustrating.

I know that they do take and make different container as you know that you can open and put your things in that have pumps and stuff like that but you still have the original problem. I can't get those types of things open.

So I was just wondering if anyone had any practical help on how to make those types of things easier? Some things I don't even use my hands for anymore at all you know picking up anything that's heavier than a can of Coke I might have to use my forearms I stead.

Things like grips or leverage grips to open jars don't work. I still can't open them. I have trouble with cereal boxes,, bags etc.. I use scissors for most things but even then cutting a cardboard cereal box can be difficult or impossible on some days.. I really would appreciate any tips tricks or suggestions.
