I'm in a similar spot, OP. I also only managed to achieve 80/120 credits on my own course, leading to my termination. I know how stressful it can be, and I'm sorry you've had to go through this.
(Also, as a side question to anyone reading this, must I notify SFE that I've failed so they don't pay me anything, or will that be sorted automatically?)
That said, as discussed already, you have plenty of options. Since you've mentioned that you had health issues, I would again look into writing an appeal to your university on the grounds that they weren't fully aware of your circumstances. This is what I have also done. With this, make sure you:
a) Clearly explain why this made your studies more difficult for you (even better if you have any hard evidence of your issues)
b) Are prepared to explain why you didn't mention this circumstance to the university until now
Also, as said before, look into contacting your course's welfare team (if one exists), your programme lead, your tutor etc. Anyone who could advise and guide you on this, and make your life that much easier. Do see this through asap, as I'm sure appeal deadlines are looming over soon.
Otherwise, don't lose hope. Your life can and will go on. This may be a good opportunity for some good introspection to figure out the reasons why you failed, whether your course is suitable, etc. This process is usually very painful and very worthwhile.
You're never alone.
