i lost my job about six weeks ago, and immediately became and anxious and started having panic attacks. i remember having panic attacks about two and a half years ago, and my doctor started me at 25 mg of zoloft and worked me up to about 150mg in three weeks time. i don't remember exactly how long it took for the anxiety to go away, i think about 5 weeks. this time she put me on 150mg of zoloft immediately. i have been taking the zoloft for six weeks now, and am not as bad as i was, but i am still feeling anxious, tightness in chest, difficulty taking a deep breath, etc. can it take this long for zoloft to work, should i be worried? it worked before, shouldn't it work again? i am still not working, so maybe that is part of what is keeping me anxious. also, would vitamins and exercise help, or would they make things worse?
