I need brain surgery

For several weeks I had been smelling smoke all the time and after a few attempts to try to find out what was wrong I had a MRI to see if I had a brain tumor.  Thank God I did not.  However, there was something in the blood veins that did not look just right so I had to have a MRA which was a more detailed look.  It was found that I have two brain aneurysms.  One is very small but the other one is just over 3/4 of an inch and needs to be repaired.
Two weeks ago this was found.  Last week I was at the Mayo Clinic in Jacksonville, FL for appointments with a neurologist and a neurosurgeon, as well as having an EEG and then another MRA with contrast.  I am scheduled for pre-op for August 7, 2017, an Angiogram on August 8th and then the type of surgery will be determined.  Either way it is brain surgery.  They may be able to go through the aorta which is a shorter recovery time, but may have to open up the skull which would take quite a bit longer.
I have also been notified that I need to be back at the Mayo Clinic on July 20th for more tests.
I live 4.5 hours away and therefore have to rent a place to stay each time I go.  I also have to have someone with me at all times.  When I go in August the stay will be at least a week and possibly longer.
I do have insurance but need help with the extra costs such as co-pays, lodging for me and my son as well as someone to help and money for gas and food.
I am a single mother who, besides working a full time job, has a small business on the side making and selling dog treats.  It is called Davis Dog Treats, LLC and I sell treats at Seaside Farmer's Market and Rosemary Beach Farmer's Market.  Both in Walton County Florida.  This is the business that keeps us afloat and allows us to have a little more than just the basics.  Unfortunately, I will not be able to receive any type of income from this during any of the medical treatment as I will not be able to make, bake, package and sell the treats.  Therefore, I will have a loss of income for several weeks.
Any amount would be greatly appreciated and every little bit helps.
God has been with me through so much in the past few years.  I know He is with me now and will see me through this.  I am not usually one that asks for help but know that this time I need it.

Thank you!
