M.S. Warrior needs help with a bill

Hi my name is Kim Diehl and I have Multiple Sclerosis and severe back and neck problems.  I have a problem with losing my balance often now.   There is way more to this than just losing my balance.  Pain every day, tired very quickly, relapses, memory problems, to just name a few.  In 2015, I started receiving disability and remained working part time until the middle of the same year, when I was so exhausted every day I couldn't continue to work.  So I sat home and rested for a year and a half.  I returned to work in January of 2017 part time because of a huge bill that needs to be paid.  This bill is for the new air conditioning unit and heat pump we were forced to replace in the house because of a defective pump, transformer, and breaker.  Water  had gotten into the crawl space of the house, the system was rusted out, and the system was covered in microbial growth, and the only option was to replace the system.  I turned this into the insurance company and they only covered $379.00 of the cost.  My husband and I are doing the best we can to make ends meet.  Our health insurance is very high and it is because of my expensive Copaxone shots I take (over 5k per month).   There have been many times he does not bring home a dime since it all goes to insurance.  I am working part time but I am struggling to keep going.  We do have family that helps  cover the cost of our montly health insurance premium.  So this is what I am asking.  Please help us pay for this air conditioning unit.  I need to slow down and stop overdoing things.  Any amount of money would be greatly appreciated.  This unit is needed because of my health problems. Thank you so much for your consideration and God Bless You All.  I would like to reach the goal as soon as possible so I can slow down and properly take care of myself.
