well as you probably know xanex is highly addictive and can be dangerous. i can relate to your post cause while i never abused them when prescribed taking them led me into alcoholism. was abruptly taken off them in rehab, not the correct way, and had a grand mal seizure. due to xanex's half life one must be weaned off them and monitored by a doc. after my experience i looked it up in the PDR. recommended use time is a max of 6 months.
in your case if nothing else you are taking it unprescribed. that sounds like a problem. and take a look at the payoff. what does xanex do for you that you can't leave'em alone? if it were a vitamin i could understand but your continued use indicates a subtance abuse problem, imho. is counting the number of days without really working for you? you're planning to be a counselor. it may be the old denial trick has you justifying your use. consider also that professionals recognize you probably have a problem also.
i'm glad you posted for input. i can't qualify that you do have a problem. only you can. but you are concerned enough cuz you posted about it. going to an NA meeting may help. you may hear someone else that is doing the same thing as you. it can't hurt to go if you are willing to have an open mind.
