I also have trouble getting into the shower due to anxiety and just putting it off You can get a tub transfer bench and a hand held shower There are agencies that help with that stuff to make a shower safer But there is no reason you must shower. You can get perfectly clean with a sponge bath and you can wash your head in the sink There are also nice smelling body wiped The whole shower thing is overrated and really not necessary, especially as we age. so its ok and nothing to be ashamed of😉❤️
