Has having the flu made me have a set back?

I’ve googled it myself and got some answers.

Anxiety even  though it often sounds like new age nonsense, it's important to remember that mind and body are connected. When the body is stressed, it's not uncommon to have stressful thoughts and experiences. Why this occurs isn't entirely clear, but every part of your body is a machine, and when something is going wrong in that machine it throws off everything.When you have the flu, your immune system goes into action, and that affects everything else in your body. Many people find that they actually start to experience anxiety before their flu hits, while others experience anxiety during and after the flu. The flu has also been linked to depression, and some studies have even shown that severe depression actually peaks during flu season.

I just got over a set back. With Christmas stress, overstimulation and the flu I felt horrible. I had crazy anxiety, the shakes, nausea, diarrhea and a few other side effects. I kept quiet for a bit and it has eased. Take care of yourself, rest and be patient. It will pass.
