I want to sure MOO for the stress they've caused me

I was diganosed with a stroke on 5/03/2012 and was hospitilized, then put in rehabilitation to learn how to walk and adapt. I was then sent to outpatient OT and PT until my insurance would not cover anymore visits. I started getting my weekly amount not counting the first week of my illness and then all of a sudden Mutual determined I needed to be evaluated again by a date they determined. Mind you, my doctor filled out their physicial form stateing I needed at least 3 to 6 months until I was to be evaluated again. I have not seen any money from Mutual in about a month. I have received papers to pay or quit in 3 days for my rent, my PGE is getting ready to be turned off, I can’t even pay my health insurance premium which covers my medication. Mutual could at least send me a check to cover the dates passed. I am not to stress, well can I sue them for that also? I am to the point of tears and it seems that Mutual does not care if they destroy my life. Can someone help me, I feel as though they are trying to destroy me?
