I'm sorry to hear of your difficulties. Seeing a counselor was a very good step in the right direction to finding an answer to your problem. When vague or unusual symptoms arise and persist, it can be difficult to identify the cause. I always encourage people to keep a daily record of their symptoms, including the time they start, the duration, what the person was doing when the symptom began, what if anything helped relieve it or made it worse, and any other data that seems significant to you. Always take the record to your medical and counselling appointments. Since an answer has not yet been identified, it would make sense to see your physician for a thorough physical examination. A neurological evaluation and a rheumatological evaluation may be indicated, to rule out any neurological or autoimmune conditions. "Brain fog" is a common complaint in certain autoimmune conditions, such as Fibromyalgia. It likely is also time to have a psychological evaluation by a psychologist. If you have not already done so, having your doctor or dentist evaluate you for "TMJ" or temporo-mandibular joint inflammation or displacement. I hope this information is helpful to you. Good luck to you.
