Injured at work, how does work comp work in my situation?

i work for apt complex as a caretaker. i work for 99 hours in a month for 795.00 of my rent compensated. out of my other job that i work 2 days a week at which are 2 checks in a month of 250.00 i have to pay 175.00 also twards rent out of one of those. i have a 18 month old and am a single mother. so those checks are the ones that i live off of. so i fell on my back and neck and now was wondering what to do... i got approved for work comp. had an mri done on neck. may be out of work for a while i am unsure how it will go but they seen some things on my mri as far as discs or something i am unsure on total results so far but... they are only gonna compensate me for 2/3 of what i made. but i worked for my rent or most of it and if i added up all the checks that they will be giving me including the ones from my other job it might be just enough for rent, if that. so that leaves me with no money for food or anything. i reallly feel that i am getting the **** end of the stick. i fell on their property on ice @ property that i was working out of office at not my own so the caretaker there should have salted. i have been in pain for days and can't even lift my daughter. does anyone know of a situation like this? can they evict me for instance if all that money doesnt add up to 970.00??
