OP, you are not nuts. These are hard times for tens of millions of people (soon to be hundreds of millions). I am in the UK and pretty much everything is shut down now, not by government order (yet) unlike Italy and France but because so many companies told their employees to WFH (or just go home and not get paid, for many), the schools and colleges have just shut down, international travel is effectively suspended for many, and, now, more and more people are getting sick and they and their families are self-isolating. I’m one of them... I have Covid-19 symptoms (trust me on this... they suck) but UK government currently will only test if you’re so ill you need to go to hospital so I don’t know if this is normal flu, something else, or the virus. I feel pretty rough but not so bad I need hospital care, and if I was really bad well I wouldn’t be on TB, would I

. Seriously, it is surreal, London in the weekday rush hour is like early morning on a Sunday, everyone I know is staying at home as much as possible, and we’re all checking up on each other’s symptoms on WhatsApp (two friends gone into hospital as acute cases so far, one just discharged but still pretty ill, other still there... both should be OK eventually I hope).
I’ve worked in London through so much madness and turmoil over 40 years, from terrorist attacks and major riots to financial meltdown and four recessions, all of which seemed at the time to be enough to bring the city to a halt. But life just carried on like before. Not this time. This is.... extraordinary. I’m also finding it hard to be motivated to play/practice/woodshed/record etc because there isn’t much to aim for (like you, I won’t be able to get together with other musos for quite a while, not even for rehearsals I think, and forget playing out) but also because I'm worried about what this virus is going to do to my family, work colleagues, community and country before its course is done. And whether or not I will have a job at the end of it. It is all a little.... distracting.
So, OP I fully share your frustration but for me it’s only the tip of a very large and sh**y iceberg of frustration! Also, I wouldn’t count on anything being back to normal by May/June. This thing has a long way to run yet. All the events (work stuff, not gigs) I had in my diary have been pushed out to October at the earliest and the big ones have been rolled back by a full 12 months. Plenty of time for me to have yet another go (yet again!) at my book of Jaco transcriptions once I stop feeling ill, all my kids are back home safe from aborted travels/studies, my business finds a way to survive, and my family are hunkered down to get past this.
Stay safe and well, all.
