In my experience with Zoloft, it took a good month or so for it to 'kick in.' Just remember, that this is only part of getting through this. For me, counseling was the most important step I took in getting over health anxiety. I know it can really hit you out of the blue. I had gone from being outgoing, loving life, running between 6-8 miles daily, and not having a care in the world to losing my self identity and actually being afraid to leave the house at times. It is really scary and confusing in the beginning but as with anything we don't know about, learning about it sheds light on the subject and makes the anxiety less formidable. Keep working through this...and keep us posted!
4 to 6 weeks usually. Some people it is different may take longer . The xanax is to help you until the Zoloft start working. Hope you feel better soon!!
