Bipolar disorder etc and currently you have symptoms of

nervousness and these are classical symptoms of anxiety.
You have underwent investigations for blood sugar, urine examination, kidney testing etc and everything came normal. So this also supports our diagnosis. Don't be distressed due to these symptoms and consult a good
