I have just been diagnosed and didn't feel as physically sick as you honey, however emotionally I know how your feeling this is too too much sometimes...love and hugs
I had to stop in here as you said you had posted here about your hospitalization............... I am so sorry you are so sick. You have been hit with a double whammy... Your URI and Crohn's, so you have every right to feel scared and anxious.
Many medicines can cause anxiety or make anxiety worse. I am sure you know that Steroids, such as cortisone, dexamethasone, and prednisone are notorious for causing anxiety.
Feeling anxious and restless have been reported as side effects by patients taking Zithromax.
Do discuss your meds with your physician and also see my post to you in A & P. (((((((HUGS))))))))
Gentle Hugs toyou my friend........and know I am right here for you.
