Obviously i can't give medical advice as im not a doctor, but i worked in the construction industry for 40 or so years and so have a good knowledge of asbestos and the health and safety required when working around it. While no exposure is good, my understanding is that its really a cumulative effect of inhaling asbestos for years before it becomes a serious health problem - the effects only start to really happen after 20 years from exposure. I know plumbers who were swimming in the stuff while working who in their 60s/70s and 80s with no signs yet of asbestosis. Breathing in some dust one time while doing diy is very unlikely to cause disease down the line.  We are constantly breathing in small amounts of it due to construction works etc outside in the air around us. Obviously avoid any future exposure, but please try to relax.
