SSRIs are supposed to help with anxiety. For example, they are often prescribed for people with OCD.
I have tried Zoloft twice--once for almost two years, another time for a couple of months. Currently, I am two weeks into trying Prozac. I'm struggling to stay on it until I next see my doctor because it is causing mood swings and actually making my anxiety worse, particularly my social anxiety. And I suspect I might be secretly bipolar II, so there's that. I'm probably not supposed to be on SSRIs alone due to that, but I have to wait until my therapist and/or shrink see clear evidence of hypomania before they'll take me seriously on that.
I can't remember if Zoloft made my anxiety worse like Prozac does, but it did make me intensely angry at times and more likely to speak my mind in a negative way. It was like my mental filter was gone.
After 10 weeks, something should be different. You shouldn't be feeling like I did, but things should be improving. I think you mentioned in another thread the dose you're on, and if I remember correctly, at that dosage you should certainly be experiencing some lessening of symptoms by now. Has your depression lifted at all? If not, it sounds like it's time to talk to your doctor about trying another antidepressant.
You may say I'm a fool
Feelin' the way that I do
You can call me Pollyanna
Say I'm crazy as a loon
I believe in silver linings
And that's why I believe in you
