Hi, for two months i have been sick with the flu, a respiratory tract infection and now im experiencing extreme fatigue, dizziness,head pressure and sinus pain and have been losing a fair bit of weight because its difficult to eat. also i have a panic disorder and my anxiety is out of control and although i know its not doing my any good im terrified because its not going away.ive been to the doctors and have been put on doxycycline but its not helping at all. any advice as to what could help me would be appreciated.
