I had issues of anxiety and depression.

Hello doctor , I had issues of anxiety and depression last year and I used to feeling tightness in left and right side of my for head (feeling in head similar to when we travel to mountain ) I was prescribed etilaam0.25 mg twice and pexcep cr 12.5 and after few days it was fine but this year in April I got covid and had lot of stress as my whole family had covid and I was terrified and took lots of stress ...so I started the medicine again as I was having negative thoughts ...and it was fine Now when I miss the dose specifically night dose pexcep cr 12.5 I feel bit of dizzy in the afternoon and evening ... What is the reason ? Any advice Just to let you know since the last year March I have been in complete isolation and I have no work since I was in tourism field ...
