When you have heavy generalized anxiety, you are usually willing to commit to that if it means there is a significant probability of coming out with an improved condition. I had such terrible panic attacks before my treatment with a bunch of different medication that I seriously considered and searched for electroconvulsive therapy and even help from shady religious institutions.
I might have gotten that desperate myself, but I finally found a great physiatrist that gave a shit and was competent. Simply taking Effexor removed my panic attacks without problematic side effects.
