Intrusive thoughts. Around me too. help!

I have really weird intrusive thoughts which make me feel like a bad person, for example sexual thoughts with family members, harming them brutally , too much worrying about them being in danger whenever they go out...i have strange rituals and fears. Like tapping on the table or anything even number of times and with equal force, straight writing on my notes, seeing patterns or outlines of my activities, seeing the spellings of words people say, repeating conversations in my head, old or new if Im going to meet someone, whenever I lie in bed with my face up, I feel someone will slash my throat, difficulty breathing sometimes, fast heartbeats ,feels like my nails being ripped off or seeing blood out of nowhere, i don't feel real many times, the world doesn't feel real, the people around me too. Help
