Donations for medical expenses

I was diagnosed with a pituitary tumor in 2011, the tumor is non cancerous. It does however need to be contained as it could cause serious problems, it can be removed but the neuro surgeon I go to says that it is a risky surgery and if it can be stabilized with medications that is the way to go. The reason I am asking for help is because I have not had medical insurance for almost a year now and the medications and medical bills from the MRI are outrageous.. The hospital has helped with some of the MRI costs, but I have had to have several in the past 6 months as the tumor was not stable. I have searched endlessly for any type if assistance, nothing is available. I am up for medical insurance in 3 months. At this time I'm drowning in medical bills. I thank you in advance for your kindness and generosity. Michelle Fleese
