do we think im going to have ativan detox??

Been prescribed ativan since end of October so almost 11 months. Was prescribed .5 mg and typically would use it around 2 weeks out of a month sometimes more. Sometimes i wouldnt take it for a week and then others i would rely on it for a week straight. This has been one of those weeks. A couple times a year i get what i call “intense daily panic attacks” — not typical anxiety but the kind of attacks that feel debilitating. Ive taken it for 9 days straight. Today i was committed to not taking it and attempting to stop it entirely but the panic came on so strong and i became immensely depressed and on edge and couldnt sit still but also couldnt lay down. I couldnt be a parent to my children! So i caved and took one. I just find it weird because previously i could go a week without or 3-4 days without.. im talking just last month and would have no issues or symptoms of withdrawal. So what gives? Did i magically become chemically rich or physically dependent in the past week due to 8 days of use in a row? If so.. what suggestions do you have to taper off and be done. I assume it wouldnt be a long taper given the fact its a low dose for 10 months and not an everyday thing. Dont want to have to rely on this med for another moment so any suggestions or experience is appreciated !
