Hope you find a peaceful place and work out if the medication is the best for you. Did you tell your doctor that you had stopped taking it before?
Ask your doctor why he is putting you on an SSRI and not a benzodiazepine? Anxiety is your issue, not depression.
When you start and stop a medication which alters chemicals in your brain, it is a guarentee that you will feel some effects. Its normal. You just have to decide if the 5-7 days of a little discomfort is worth it for feeling better in the end. I am also taking an ssri for anxiety. I was perscribed it because the chemicals responsible for cause depression are also responsible for causing anxiety. If the chemicals in your brain are in-fact, out of wack..then an ssri should help. I take a benzodiazephine on an as-needed basis.
