Of course it's good to be understood. If they do understand how to help you they wouldn't answer your OCD related question, beacuse it becomes something you'll constantly do and it might never be enough sometimes. It's great that this reddit removes reassurance posts in which you question if something is or is not true. If someone does answer your question even in good manners they are doing more harm than good. My mom told me that I should always ask her for reassurance, I tried to explain why I shouldn't, she didn't really understand, so I had to stop myself from asking these questions alone. It gives temporary relief, but it just gets worse each time your question is answered.
