I hope you're feeling well [closed]
If there are no health problems you are alluding to, simply say, "I hope you are well."
Saying "I hope you're feeling well" does, as you intimated, give the impression that you are worried about your friend's health.
Grammarly also has some suggestions for ways to avoid this style of greeting altogether, as it tends to be overused and may come off as insincere.
