hello! person with ocd and hypothyroidism here! usually i try to use exposure therapy when it comes to my obsessions, but this sort of method doesn’t work for everyone, especially those with worse intrusive thoughts and stronger obsessions. for instance, i like volumes for tv’s, radios, etc., on multiples of 5. sometimes i will turn the volume to, say, 27, in my car and just keep driving and try to forget about it. it doesn’t always work but sometimes it does and it helps a lot!
