I am worrying about having done something by mistake in past and because of that mistake it could really bleach a person's privacy whom I know and is very special to me. I always get thoughts of "what if you had done it by mistake" and worrying about consequences ... these thoughts come to my mind every minute and its been 30 days since that thing happend to me and I spend my whole day thinking about that and now I fear I wont be able to perform any activities in my present like my exams because I wont be able to focus due to those intrusive thoughts. Please help me.
