Do not hesitate to go in the type of store which sells medical equipment (wheelchairs, contention stockings, etc. – not that that is what you need) to find out if they have equipment that might help you.
Opening jars is… well, you know! There are various jar openers and some may be a bit expensive, have a type of shelf lining that is a rubberized material that is a bit sticky on a counter. (This idea gotten from hospital staff.) You cut two pieces, put one on the counter on which you will put the jar, use the other one to unscrew the cover. (This type of material can also be used to put under a cushion on your sofa or chair which tends to move around – it will keep it stable for longer periods of time.)
Please rethink about “looking good” and do not hesitate to use a cane (or canes) when walking because it will make you look old. We often suffer from vertigo, our muscles go out of whack, our knees or ankles give out – better look old and interesting than end up with a fractured hip! You may end up looking “interesting”. Walking with canes has its problems: you may develop blisters if your skin is overly sensitive, have nifty little cotton gloves – sometimes two to a pack. You may find handling the canes hurts your wrist : get a wrist stabilizer from your pharmacy or med equipment store.
My doctor – whom I will not qualify, but I’m stuck with him since doctors are hard to find in Quebec – tried to make me trouble with the authorities that issue drivers’ permits who regularly ask for reports. If you go to see your doctor and have decided to use a cane, tell your doctor that it is more to ensure balance and for prevention against falls (my doctor is very ignorant about FM/ME/CFS).
Oh! There is a “cane-seat” you can find, sometimes even in pharmacies. I hardly ever leave home without it: believe me, it’s better than MasterCard! The “cane” has three legs and the middle one is the one that touches the ground when it is closed. When you need it to sit if you get too tired waiting at the cash or such, you open your seat. However, you must be wearing pants because you have to sit with the handle between your legs for safety. They are not overly expensive and can take quite a bit of weight (I’m over 200 lbs. and have been using mine for nearly 10 years).
If you take various meds, you may be taking some that affect your capacity to endure sunlight : get cute summer hats or caps. This is very restful for eyes also (are we ever sensitive!). With straw hats, if you’re afraid it may go flying in the wind (we don’t see many days without middling winds nowadays), you just get two pieces of ribbon and put it through between the crown and the brim of the hat, make a little knot so it stays put, and tie it on windy days. When it’s not windy, just leave the ribbon under the hat.
If you can afford it, get Obus Forme type of seats and backs to use in your car. They afford quite a bit of comfort.
Shoes: if Crocs are still in business, they just can’t be beat. The imitations are a no-no however. (I have 14 pairs and dread winter because I never found the Crocs boots…) They have various models, sandals, mary janes, etc. The original ugly model is actually the most comfortable. For winter, they have a lined model which is really cushy.
Cooking : when having good days, cook batches that you can freeze. Wash more lettuce than you need, spin it dry (a spin dryer for lettuce is great, but you can also wash lettuce, put in a large strainer, leave it there for a while so most of the water falls from it or evaporates – then put lettuce in Ziploc bags that you have lined with paper towels).
If you find that opening cupboards and drawers for your everyday items is sucking up your energy, if you have wooden cupboards, screw in hooks and hang your most-used utensils. Your kitchen will look interesting, if not totally tidy. Or if you have wall space, you can get a board with holes in it and there are various hooks for that type of board.
Windows and drawers are hard to pull, get some Jig-a-Loo spray and it will make things easier.
If your neck is painful and you need to be sitting in a car (or elsewhere), you can find U-shaped little cushions that are inflatable in travel stores. You may also find that
I-shaped inflatable cushion that you put between your knees to sleep.
There are many many more ideas you can find when you dig up in your imagination. Even for those of us who have cognitive problems, it seems that if we have used our imagination, it is still there. Memories fade, learning is difficult, but what you have acquired should still be there inside somewhere.
