Okay thanks a lot there. But i have one more thing to ask.the day after this incident happened i accidentally popped a big pimple around my cheek and it bled quite. I went outside after that without attending the bleeding pimple because it was not painful. Now i have got a habit of wiping my nose, eyes and cheeks ( gross i know) every now and then.. So i am worried because if i had touched hiv blood laying anywhere outside(public transport)and then accidentally rubbed my hand against the bleeding pimple. Sorry if i may sound crazy but i am loosing sleep over this.. I have an exam but cant study please help me out.
