Just with little game or physical activity i get exhausted and no energy is left in my body. I have brain issues like difficulty thinking,concentrating, memory loss, and have been taking antidepressants but they don't help me with concentration issues. I also have brain fog where its very difficult for me to understand what is going on around and to process things in mind. I have hypothyroidism but its under control now with TSH 3.5 . But these issues are not improving. I have these for last 7 years. I also have blood pressure in the range of 130/90, How to treat this condition.
