No need to despair about not making the meeting with your group. It happens. If you put your fair share of contribution in in other ways, it wont matter greatly in the scheme of things. You can do that. I know it.
Sorry you're not feeling well, it's hard to get motivated to do stuff when you feel sick. But you've done well by doing the quiz, so at least that's one thing ticked off the list.
I love ticking things off a list - maybe you could make a list of the things that need doing over the next, say, 2 weeks ... as you tick them off, it will feel good. Include small things (readings, going for a short walk, etc) so there's lots of ticking being achieved!
Maybe you could do one or two little things between now and Monday to start making the baby steps towards your assessments. And that's an important thing to remember, Baby Steps. Each little tiny thing you do will get you closer to completing your tasks.
If it's nice autumn weather over the weekend, maybe you could spend some time working on your new raised beds - it can clear the head to be out in the fresh air - and now you have your screening up (yay!! Well done!!) so you have some privacy!
You can do this MF. Just keep chipping away at it.
We believe in you, so borrow some of our belief if you need to for now.
