I'm worthless person.

Because of my mental ilness (OCD) and severe asthma I need to postpone my exams for The third time.I study finance at de montfort university and they will throw me out if I don't pass any of 5 exams that i'm supposed to sit this year.Last year I deffered exams two times because I was and i'm still sick and because of that I need to defer my exams 3rd time to August.I'm in my third year,I can't calm my nerves even if I talked to the faculty admin that I can postpone them third time, I have horrible suicidal thoughts and i'm insanely anxious,my life is falling aparat because of my ilness.This year my mom had sepsis and is still disabled, I'm Polish and when I came to UK I was working like a slave in the factory just to pay the rent and eat once a day.Please can somebody tell me that dmu won't punish me for having mental ilness and I still will be able to write the exams in August.Please tell me that they will treat me like a human being and understand that i'm ill and in distress.
