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...

I've had this app for awhile and was really nervous to post,comment or like anything.I still am,and frankly I've been having a really rough time which mostly includes ocd symptom,guilt/shame and agoraphobia which is not a fun combo but a small part of me is so tired of hiding and feeling awful all the time,even if at times I feel like I deserve it.I've been wanting to dabble into my hobbies like drawing or gaming but even my hobbies have been stressful & these negative feelings have been so awful for so long that I feel like I'm standing between two roads all the time yet feel horrified and worried either path when it comes to almost any decision will be wrong or not worth it in the end(and I hate that I feel like so.).I'm sure people can relate but the heavy loneliness and dehumanizing feelings is so awful,it's so good at it too.😭 I'm not diagnosed yet but I share alot of symptoms (interested to figure that out about myself soon.),but until I get medical insurance figured out I don't think I'll have access to professional help yet so for now I've just been watching some professionals online and I might finally read 'Freedom From Obsessive Personality Disorder' and see what it can offer.ANYWAYS,I'm trying to force myself to post so I can to people irl and online in any way I can train my brain to not stay so terrified of everything/everyone so,how has your day been?I hope it's been going well,if you've read this book or have any good suggests please feel free to let me know!
