High TSH levels, shortness of breath.

Whenever I exercise even a little , I feel extreme shortness of breath. Last whole night I could not sleep because of it and now also feeling short of breath. This condition has been on and off since last one year. I used to take inhaler thinking I had asthma as my father has asthma. But I got my checkup done and found that I have extremely high TSH levels(610 uIU/ml) , cholesterol total 329, Liver SGPT 89 . I got the checkup done using healthians app but they said my TSH level has not been tested well. So I have given a new sample today again. But after reading about hypothyroidism now I am scared that those results might be true. Please suggest me what to do. I could not go to a doctor fearing covid. But after getting my new report today I will go. Can someone tell me if all these thyroid symptoms can  be treated by medicine?? I am really worried as I am very young. I was fairly active before lockdown started. After lockdown I did not do much exercise. Plz guide me.Feeling hopeless.
