The common possibility I can think of in your case is depression
. However, it might be worthwhile to get a couple of investigations like Vit B12 levels, blood sugar levels, thyroid
function test , Complete blood picture, Serum electrolytes done as thyroid disorders, hypoglycemia
, electrolyte abnormalities, anaemia, Vitamin B12
defeciency can all present with symptoms similiar to what you are experiencing now.
In the meantime, sign up for yoga/ relaxation classes which might help you relax .
Hope this helps.
