Anxiety and sleep issues post covid.

Hi, I am having a lot of anxiety post Covid(2 months since symptomatic) almost a month now. it triggered as I was worried for post Covid symptoms my father and I were facing. in my case I am still facing lot of gas all the time. I have big sleep deprivation as I am having sleep for only 2 hrs most of the week. Rest day I sleep only due to exhaustion. I feel discomfort during days and thoughts keep coming. At night I am restless and can't fall asleep. I tend to get out of bed frequently. I feel sweaty sometimes and chills post sweat when air touch body. I tried counselling for last 2 weeks but not getting result as I am too exhausted. I am worried for anxiety and sleep medication as I feel I might get addicted and their side affects on long term use. Combining all is making my life difficult as I can't focus on my job and I can't seem happy. I don't feel indulging with all my relaxing activities and with health issue have lot of restrictions with foods I liked to eat. Please suggest.
