(((mars)))) actually, this could be a good thing! Often the antidepressants also help some more with the panic (too.) New stuff is often anxiety-ridden, but I agree, 3 weeks is too long a time. The meds don't just quick change you overnight, you build them up in your system. (They DO begin to work immediately, but we don't usually sense any change for weeks.) So, especially with the holidays coming, you might really want to begin soon.
