a month of cold like symptoms won't go away help !

Hey people.. my name is Juan im 38 years old and pretty healthy overall .. never really had health problems in the past but lyme disease about 2 years ago witch has been under control by doing test every year. About a month ago i developed a cold or cold like symptoms , the classic runny nose , sore throat and body aches .. never fever or caught or any other symptoms .. after 2 weeks i finally saw a family doctor , he did noticed inflamed throat and did a test for strep throat that came out negative ,. he told me to rest , drink fluid , salt water gargles etc.. since then its been on and off .. some days i feel ok and some days i just spend the whole day in bed like if i had a cold again .. like my body its fighting something .. in 2 days its going to be a month of this and im starting to freak out .. I made an app with a sinus specialist but they wont see me for a month because of course all this corona virus going on now in NYC . I stared doing saline spray twice a day and i do feel like theres a lot of mucus coming out .. just transparent so that rules out any antibiotics i guess.. today i woke up super fatigue and worried and i dont know what else to do .. should i go to the hospital .. any advice will be very appreciate it .. my anxiety level starting to peak many thanks ! be safe guys !
