Hi, I’m sixteen years of age and ever since I was 7/8 years old I often get this feeling that I have to do something otherwise someone I love will die or (this might sound silly) but I sometimes feel like I have to do something a number of times or count to a certain a number a few times because I feel like if I don’t, the boy I like will stop liking me or never ask me out. For an example when I was younger I used to have this obsession of running from my room to downstairs holding my breath otherwise something will happen. I also sometimes get this paranoid thought that when I’m on my phone, that the boy I like is watching me through my phone camera, so I always have to change the front camera to the back or I move my phone to lower down or to the side so I can’t show my face. Another paranoid feeling that doesn’t happen as often is before I leave the room/house or about to turn the lights off I have to check everywhere to see if anybody is hiding there, even if it’s a small space. It’s really annoying, but I actually can’t stop. I’ve tried a number of times before to ignore the feeling, but I failed after a few attempts and sometimes I don't even realise that I'm doing it. My mam told me that she has this as well, and also my sister and aunt and a few other family members but different when it comes to the things they do. My aunt has to knock on the door when she leaves the house because she thinks that someone will die. I would really appreciate it if you informed me on what I have, and how I can get rid of it.
