Alyssa's brain surgery

My fiance's name is Alyssa Butcher. She is a 22, about to be 23 in July, student. She has been a migraine sufferer for about ten years and went to the ER one night because a migraine got so severe. She was told she had a mass in her brain. She was transferred to McKinney, Texas Baylor hospital where she was given her diagnoses. She has an AVM which is an arteriovenous malformation, basically a mass of arteries and veins that causes hemorhaging and anuerisms in the brain. We were transferred to Dallas, Texas Baylor hospital from there and met our brain surgeon who will be performing brain surgery on May 21st. We are currently both employed but she will soon have to let her job go due to the surgery and be out of work for eight weeks. I will also be taking off work in order to care for her for the first couple weeks, her parents and my parents will help with her care post-op as well. We have already accumulated several bills from hospitals to doctor visits to care-flight rides and the co-pay for before surgery has yet to be paid. My fiance and I have been together for four years. There is nothing I would not do for her, any generous donations and or thoughts and PRAYERS would be greatly appreciated. If you do leave donations if you would leave your name and address for thank you letters. God bless
