How do I effectively use this app?

Hello! I just got diagnosed with OCD a week ago and joined the app today to find a sense of community. Since my understanding of treatment is minimal at this point, I'm confused why everything on here tells us not to seek or give reassurance? If someone could explain the reasoning behind that it would be greatly appreciated, as I want to make sure I'm not only watching out for it in my personal life but also using this app appropriately.

New to this app. Do members find it helps, I'm worried I will start obsessing over things I hadn't thought about before when I read other people's OCD triggers...

Ok so I just downloaded this app like two days ago because I was looking for a OCD specialist. Maybe this is just my opinion but the posting’s on this app can be super triggering. If feels like even sharing your experience on an app like this can contribute to fueling OCD. So many people I see reassurance seeking, confessing and posting the same things multiple times to gain certainty. Makes me wonder if this app is counterproductive to the point of OCD treatment. I’m guilty of spending hours scrolling through the post trying to find people who relate to me, but in the end it makes me more anxious and fuels my OCD. Idk what do you guys think.
