You don't really say what it is you're feeling, but I'm wondering, did your doctor recommend a therapist before putting you on a strong drug like Zoloft? Is he a psychiatrist? Do you feel your life is so impeded you need medication or do you think you just need to get over the effects of the things that triggered this? Doctors these days hand out antidepressants like candy, it gets you out of the office, but your doctor does know a whole lot more about medicine than those of us on here. If you don't think your doctor did a good job, get a second opinion, or see a specialist. But starting medication is a big step, it can be a lifetime step, and you might be a good candidate for medication but it's not the first step for most people. It's there when things go out of control, not for every time a person feels life is getting difficult. You know better than we do where you fall on the scale of how much your life is being disrupted, and whether this is the first step you think you should take to get over this anxious thinking part of it. But as for the physiological part, again, you haven't really described it that well. If the Zoloft is making it less of a problem, it might indicate you are suffering from anxiety, but antidepressants can also make people just not care as much about their problems without necessarily be addressing the problem.
