Xanax

I’ve been on benzos for 20 years bc of panic attacks and agoraphobia. 5 doctors all said I gave one of the worst cases of panic disorder they have ever seen. they all recommended Xanax. My question is I told them how would i ever get off if I needed too (they don’t recommend it and prescribe me .25mg up to 4 times a day) , they said very very slowly. They said by breaking tablets into smaller doses every couple months, however when I told them I’m on .25mg and I take 1/2 half a tablet a day once a day that they told me that’s lower than a kids dose and my addiction is just in my head that half of a .25 isn’t dong anything to help or harm my anxiety nor cause major withdrawals
