Yehudah Tzvi,
I’m sorry your friend couldn’t come, I hope he’ll be able to make it soon. Do you have any other local friends you may be able to invite? I’m glad you’re attempting a shower. The fact that you’re attempting to do something difficult shows that you are not in a depressed giving-up mode of thinking. Good for you! And if you do manage the shower, I’m sure that feeling fresh will further lift your spirits. If you can’t do it in the end, try again tomorrow!
Refuah Shleima and we will continue davening for you.
