I wonder if it would be helpful to speak to the course co-ordinators early and hopefully they can be more supportive of you as you progress through the course? @Pinkgal
I certainly did that at the beginning of each unit I studied. I emailed them to let them know that I may need a bit of extra support and they were absolutely fine with that.
Having those anxious nerves is totally okay. I haven't completed an assignment in over a year and last week, I had to do an assignment - it felt so weird to do it all again and I felt those nerves too!
I took deep breaths throughout the assignment so that the anxiety wouldn't overwhelm me.
I'm glad to hear that you are finding ways to keep grounded.
Also, it is understandable you are still thinking of your friend. In a way, it was good that they were able to let you know directly. Better than people ghosting someone so that there's no closure...
You are on the right track. Just keep going.
