I'm  a 21M who tested positive in mid Jan. I had a very mild COVID case. The  only symptom that remained was a sore throat and palpitations.  Immediately after recovering, many times before I slept my heart would  keep thumping harder, maybe faster. I'm unable to concentrate on  anything. It was kinda intermittent just after recovery, mostly  disappeared and now has made a resurgence once I started studying hard  for my college final exams(customary last minute learning). Now its non  stop, for 3 days every moment in my waking hours has been spent in this  kind of anxiety.

Few years ago, I  developed stress and many mental problems after not succeeding at an  important exam in my country. I even developed dangerous thoughts for a  while. Few months later I got over it and I only got brief anxiety  attacks a day which faded away within a few minutes every time, by  drinking water, listening to music, exercise etc.

Now  I don't know what to do. No amount of music, relaxation, meditation,  water, etc. seems to be helping me.  I have an intense, excessive and  persistent worry and fear about everyday situations.  Sometimes I see  somebody on reddit have a bad life experience and I then imagine myself  in similar situations with imaginary fights, conflicts, injuries, death  etc. involved, despite me never being involved in any fights or violence  in my life. I'm fairly sheltered. Turning off social media doesnt help,  because when i watch a movie or a soccer match and see any conflict  there, the anxiety heats up again. And of course I cant ignore all this  and work as I used to be able to do, because its now constant and not  intermittent.  Ive been pinned down to my seat in front of screens  almost paralysed by the stress. Its not even like im burdened with work.  I had only like 2 hrs of work to do, home and college related. Unable  to do any of it.

**Should I see a doctor? If so what type?**

Are there any medications that would temporarily mitigate this feeling?

If theres any better subreddit for this, please point me to it. I've posted this on many subreddits.
