Hello Doctors, 4 months back I started feeling sick like dizzness in head, loss of balance sometimes(very rare), palpitations, shortness of breath, feeling really scared while hearing if anyone is dead. I thought I was not well and went to neurologist, they suggested me medicines for dizzyness.. It Didn't got cured, later 2 months I went to another doctor, he took bloodtest and found vitamin b12 -150ng and also I had vitamin d3 deficiency (17.5). I used medicines for 2 months (Methocolabalmin) and vitamin d3 syrup.. I feel very much better but still I am feeling scared about deaths of present pandemics happening and I am feeling dizziness in head but palpitations almost cured.. Please suggest whether I am normal? Still  how much time it takes to get cured? Thank u in advance
