greygoose, i really feel for you. you know "rationally" that there's no way that bat could've bit you. you have professionals who've told you that there is no way your cut is a bite from a bat. yet, still your anxiety/panic keeps that possibility alive...
i, for years, had massive panic/anxiety. my panic has all but stopped. know what worked for me? i learned to play the "what if" game all the way out. i would have one question in my mind send me into panic...maybe something as simple as "what if i don't get the laundry done today"...boom panic. however, since i've learned to play the "what if" game all the way out...very few things cause me panic.
it was just that simple for me...my mind was doing it, so i found a way to work my mind to its fullest extent.
