Severe anxiety & cardiophobia post COVID

I had the first symptoms of COVID on May 7th. Suffered mild symptoms (occasional moderate fevers, cough, etc) for over 10 days, before I began to recover. While most inflammation indicators were ruled out through blood tests(CRP, ESR, etc), I occasionally suffer a mild cough and slight rise in temperature (=<99 degrees) even today, say once in three days (I get the symptoms at night and it gets better in the morning). Not sure if these symptoms are are a matter of concern but they get me in this thought loop - it reminds me of long COVID and how people die even months after, due to the various after effects. This thought loop causes me to develop symptoms like vertigo, chest pain and punchy palpitations and these mark the beginning of an epic downwards spiral every single time. I have had cardiophobia for a long time (was in control until I got COVID). I still keep thinking of heart attacks and strokes. Should I be worried about any of these mild symptoms still?
