I feel desperate. A month ago I had sore throat, I quarantined myself ( I live in a big household) for 21 days. I went to doctors a few times, all said I should be cautious even though I got tested negative. So I lived in my room, every day being scared to death that I can't breathe, having chest pain and such. But no fatigue or body ache or fever. I didn't have a serious symptom, just mild and probably only in my head ( I do that sometimes). After 13 days my worries passed and I felt completely fine. The day after quarantine I went out and I didn't have encountered with a lot of people, but 3 days later I started having sore throat ( it started exactly the moment I thought my brother has covid, which he didn't) and feel like coughing ( maybe 3 coughs everyday). I couldn't dare to quarantine because my family would think that I've gone crazy. So I've been living in fear of getting worse or giving covid to others in the last 5 days. No one has got it and my symptoms hasn't gotten worse but no improvement either. Is it all in my head? Is it covid? I can't stop thinking about it? I've been so cautious in the last 17 months and now that I'm close to getting the vaccine, I'm going crazy? Please tell me what to do?
