It’s all in my head?

This past few days I’ve been feeling off. It all started on Friday night, I took a sativa edible. Normally I would take indica but I ran out and this was all I had left. I didn’t like the way it made me feel so I went to bed, no problem really. When I woke up the next day, I had chills, sweating, I thought I was coming down with something, so it freaked me out and now I thought I had to deal with something like the flu. The next two days were the same but I showed no obvious signs of infection like fever, no symptoms at all really besides feeling hot and cold to the littlest temperature change. As well as not being able to sleep. I thought there’s no way that I’m sick showing little to no symptoms because I’m vaccinated. Come Tuesday morning, I wake up feeling nauseous. Didn’t feel like eating anything. So I came to the conclusion that I was withdrawing from my edibles. It made a little sense. The next night, I finally took my normal edibles again, only to get nauseous and anxious again. Same feeling into the next morning. Now I was completely lost, how am I still feeling like this? My family blames it on my lifestyle and anxiety, being a complete hypochondriac and recluse, but I still feel so much physical pain and stress. Is that really it?
