Groggy, irritable, flu like symptoms, ect

In recent years I have noticed how bad I feel when I wake up. I get the symptoms stated in the title but the flu like sticks out . I wake up feeling foggy, nausea, irritable, feverish symptoms, ect. They last most of the day but aren't as bad as when I first get up. I have noticed that my sinuses could be playing a role as my sinuses are always blocked up especially at night. Anyone recommend some over the counter medicine that could help that or maybe target something else.

Btw, I am a healthy eating and active 17 year old. I also work out regularly. I do also have anxiety problems but I don't feel as though they contribute to it
