Hello doc, I have a few questions regarding symptoms that have been occur lately. I have taken a blood test and come up negative for any thyroid issues as well as ruled any vitamin or mineral deficiencies, along with being tested for hepatitis which has also come back negative. I have experienced excessive sweating, nervousness, insomnia, mild depression, lack of motivation, general fatigue, rapid heart rate (situational) and have become incredibly withdrawn. What do you think it could be, and if the answer is anxiety, what are some cognitive behavioural methods you would suggest attempting to get over whatever the condition may be?
