I would not stress. Your company, your union and your insurance(s) should look after you. Even if they don't, the 'echo' will probably give you the all clear. Even if it doesn't, there is nothing you can do about it, it is fate. So relax and start having a general think about 'what if', and how you would cope, e.g. apply TDODAR
I have been in the situation where the airline I was employed by went out of business; my salary stopped abruptly, and I had to start all over again and pass the selection process for another airline. This happened with two airlines, one after the other !!
Then, as I was part way through the pilot selection process for the third airline, Covid struck, so that was the end of that. We couldn't get new employment, owing to rampant ageism everywhere, (yes, it is illegal, but employers find many ways around it), so we couldn't pay our mortgage. So we decided to sell our house and downsize.
This was a major disruption and abrupt change of our life plan, but, actually it was fine. It turned out quite well and we survived quite well.
So, try to relax. It will probably just be a temporary period of sick leave, but even if the worst happens, you will survive one way or another.
PS, if the worst does happen, remember to talk to your mortgage provider straight away; they will almost certainly allow you to pay interest only for a period, to give you a little more financial margin.
