The damage is not irreversible, it just takes a while ( a long while) to heal and you have to stop all benzos. Starting and stopping them is probably the worst thing you can do if you've already experienced withdrawal. I got cut off of Xanax after using daily for ten years...it was hell, it took two years before I was feeling noticeably better, and after going on seven I am almost back to normal with exception of my memory. It's not an easy recovery but it is possible.
CJ - getting back on benzos isn't going to do much for you at this point as most of the damage from stopping has already happened. When you stop and you don't do a nice slow taper your body can no longer regulate glutamate properly which then becomes excessive and it does very real neurological damage...that damage has already occurred. By taking benzos again you are possibly preventing that damage from healing as neurological tissue does not regenerate while benzos are being actively consumed. While you may feel your anxiety level decrease for a while, the anxiety will not go away and you will build a tolerance quicker. Benzos also kindle, so each subsequent withdrawal is worse than the last one. I wouldn't risk it if I were you. Find your inner strength and remember that this truly is temporary. I know how bad it sucks - words are inadequate to describe the physical and mental pain but it does get better. You have come so far, relapsing is not going to improve your situation.
I know it feels like you are losing your sanity but this is normal - you're not. Your sanity and rationality will return. I think that's kind of a good sign you're feeling this way so soon, I didn't get to that point until about six months in, though I think withdrawal initially rendered me so stupid I wasn't aware of too much.
