Helping and caring for people with Lyme and other tick-borne diseases is very, very difficult. It is a MARATHON, not a sprint! It will take a great toll on your body and life. Giving support: First and foremost--believe your loved one. They are not faking it.
Second, never give up hope. Keep trying to find care from people who know how to help you.
Watching this will make you cry. Have another person with you if needed.
