PS, I've struggled with anxiety and depression for about half my life now. For most of this time, I've been treating it with various SSRIs (from Zoloft to Prozac to Lexapro). Recently, my GP added Wellbutrin to the mix and that helped A LOT. It targets different receptors. I've weaned myself off the Lexapro because of the side effects, and seem to be managing pretty well on just the Wellbutrin. Just a thought, in case just SSRIs aren't working for you.
