Hi Bruiser and welcome!
Wow, you have really been through soooooo much... My heart goes out to you. Part of your post reminds me of what Traveler went through with taking antibiotics which gave her a messed up gut.
You still can get better, please don't lose hope! I have been well for several years and learned a couple of things, one of them being is that when the brain is affected it's not permanent. Let me explain what happens inside there:
When lyme bacteria die they leave toxins. One of the worst toxins is ammonia which affects our brains. The good news is there are natural supplements you can take to bind up all that ammonia so you can purge it out of your body. What helped me clear out that ammonia was Dr. Jernigan's Neuro-Antitox Formula (I took the CNS/PNS formula).
You may want to read this article below (I am not affiliated with Dr. Jernigan or his botanicals in any aspect):

Ammonia not only affects our brains but our joints, liver, etc.
Hang in there okay?
