Constant Fatigue, disrupted sleep, loss of appietite?

RandomGirl Asked: Constant Fatigue, disrupted sleep, loss of appietite?

Ok so for the past 2 weeks i have been really ill. It started off with a sore throat that when something cool touched it, it was a relief then i ended up having a flu but felt really nausea also. I went to the doctors and was given an antibiotic and it didn't help as i had really bad chest pains and cough with snotty nose. Now the flu has gone but i still feel extremely fatigue and can't sleep well and have lost my appetite for over a week now. It scared me so i started to google my symptoms and told me i had cancer, heart problems or other stuff. I also went to a+e had my heart monitored, blood pressure took and glucose test but then the doctor said everything was normal and he thinks i;m just very stressed and to chill out. I do suffer from health anxiety but i have always been better after a few days and this fatigue feels different. I am forcing myself to eat now as i know i should but just wish i could feel normal again. Should i be worried??
