I'm scared I missed too many of my A Level exams and I can't focus anymore

I made another post about this. My health has been bad and I missed some exams. This is my resit.
For one subject, i missed 2 out of 3 papers. Luckily I already have the grade I need here so it doesn't matter.
For subject 2, I've missed one paper and I will go to the last two. I need both this subject and the next.
For subject 3, I will only be able to sit paper 3. Biology paper 2 is tomorrow and I know I probably can't go.I read somewhere you only need to sit 25% of the subject to get a grade. Paper 3 is 70 marks so 70 out of 270 should theretically be enough to get the grade I need if I do well. But, i've always been weak at paper 3 and I'm scared of my application getting rejected. I can't stop thinking about the worst case scenario and it's making it hard to studying because I feel like it's already game over even though it isn't. My uni does not take special consideration into account but I know my insurance does ( I picked it because of that).
I'm so scared. I just need some reassurance.

Regardless of anything, if your insurance takes special consideration into account then the worst case scenario may be that you don't go to your ideal uni. However, you will still get into university and be able to study your course, and it's definitely worth calling your first choice uni on clearing to see if you could get in on lower grades.
Do the best you can but give yourself some slack and try not to stress, just focus on your health. There's still a decent amount of time before paper 3 for you to revise and do past papers and practice questions, it's entirely possible for you to still do well even given your difficult situation.
Good luck

What offers are you holding at the moment? By which I mean - which grades do you need for your firm and which grades do you need for your insurance?
Do any of them specific which subject they want which grades in?

My insurance is still pretty high. The grades I need are ABB. Thank you. I have some time which is good. I think 5 days to bio paper 3.

My firm needs AA and my other ABC. I already have a B so I need AB at a minimum in biology and chemistry. I'm sure I can crape an A in chem. If I get close to full marks in both papers, any special consideration should boost me up to an A since I only missed one paper. Biology is what scares me. I will only sit paper 3. I just missed paper 2.
