failed third year and don't know what to do?

During first semester, i had a lot of personal and financial problems that i have spoken to my tutor and university about in that semester.

They advised me to either fill out a suspension form, to retake the year or to carry on into second semester and try to balance out the modules from first semester.

After speaking to my parents, i decided to carry on with my second semester however because of first semester. I was depressed and barely leaving the house and when i did leave the house i got severe anxiety always thinking someone had something out for me. I had not spoken about these anxieties with the university staff however here is where it takes a turn for the worst.

I had 3 assignments including my dissertation which were all in for a space of about a week, during that week one of my friends commited suicide and i had to go back to london from hull and the day i got back to univeristy.

I found that my house had gotten broken into and they took everything of value including my laptop and usb. At this point i was distraught since i couldn't handle the 3 assignment workload in a week when they each were originally 2 months.

I managed to complete a barely passable disseration topic and finished off one assignment however i found out today from university that i cannot appeal for mitigating circumstances on the ground that i had submitted something.

I wasn't informed on the rule where if you submit something you cannot apply for mitigating circumstances. I was always under the assumption of something is better than nothing.

So my worry is how likely it is for university to allow a third year student to retake if he had failed every single module of that year? My personal reasons are valid but are a bit difficult in finding evidence to support my claim
