About 8 months ago after my post graduation , i decided to prepare for goverment exam at home , but i don't get the  positive environment which i  thought, my relatives and everyone started asking me what you are doing now , when you are getting married ? These all questions and my failure in 2 -3 goverment exam , created a stressed , i fell like what i am doing , my life is slowly getting destroyed and i am unable to do certain small things which i usually done easily and doing things like writing and reading makes me feel very hard to do , i want to study but i am unable to do that I always feel less energetic , sleepy , and i also got a panic attack 8 months ago , i started overthinking that leads to this condition of mine an anxious mind . I consult a doctor and i also done my CT scan of my head all things are normal , i was diagnosed deficient in vitamin D and Vitamin B12 . I aslo take amitryptiline , should i continue with it or i should need any other consultation .
