Hi and welcome, @MySunrise , it's good you've joined, where people can understand what you're going through.
The good news is, you're already on the peer support forums for those topics... There are people here with DID (I'm not sure what DIDnos is), and childhood trauma. I don't have DID, but I have complex childhood trauma. I always dissociated, from a child, but I've thankfully been able to work through a lot of my childhood trauma, and hardly ever dissociate now.
If you were asking about offline peer support forums, in real life, I'm afraid we're not allowed to recommend specific offline support groups, due to the rule about anonymity on the forums, here . It's to keep people safe and allow us talk about our mental health safely on the forums here.
You can type 'DID' or 'dissociation' into the search bar, to find threads on those topics (or any topic). Another forum tip is if you type @ and then click on a member's name in the drop-down box, that person will get a notification that you've replied to them, like I did for you above.
Welcome also to @rubyrose ...hoping you also can find what you want from the forums 🙂
