Hello, My Name Is Kim And I Am 53 Years

Hello, my name is Kim and I am 53 years old. I was diagnosed with chronic Lyme's Disease in 2009. I was treated with various antibiotic for a year and a half. Since that time, I have not had any further treatment,in part due to moving to another state and not being able to find a physician with the expertise in the treatment of Lyme's Disease. Although I no longer have the fatigue, joint pain, etc., I am still experiencing problems with my memory, irritability, sleep disturbances on occasions, and at times bouts of unexplained anger, which is out of the norm for me. I, also have difficulty at times with speech due to not being able to recall the words I wish to speak. Is it possible that I have had neurological damage from Lyme's Disease?
