I got a great answer but I was threadjacking so I thought I would see if anyone has some additional helpful tips or experience.

Wellbutrin has worked for me for a while, but it doesn't seem to be as effective any more. Also I can't find anything for these random anxiety attacks (physical symptoms are constant, it seems). So I managed to get myself off to the GP. She has given me a prescription for Effexor. She didn't tell me to wean off Wellbutrin.

I took one and had horrible anxiety all day. It was horrible. So now I'm scared to take any more (I am still taking Wellbutrin). I am not sure I can handle the 2 or so weeks of getting used to a new drug.

So, should I give it another go?
I suppose I'm also scared that I will just sink further down without realizing it (and, so, be unable to reach out to tell anybody).

And I am scared that this is as good as I can get

Help, please.
