Hi
I'm new here. I came as I needed a place to learn more about PTSD, anxiety, anger management, etc. I have a trigger with a very toxic, belligerent relative, so I'm trying to find ways NOT to snap.
@nycdb20707 Welcome!
I hope you can find all the stuff you're looking for on this site
I know it can be a bit daunting to navigate, so I'll share some links for you if it makes things a bit easier 
For PTSD: there is the forum community here (which is a section of the Traumatic Experiences subcommunity) and there is also this guide to learn more about traumatic experiences here
For Anxiety: we have a subcommunity for Anxiety here as well as a couple guides as well (a general guide, one for social anxiety , one for test anxiety, and one for panic attacks) and there is also a group chat for anxiety too, where you can have a live chat with many people, both listeners and members (you can find it under the 'group support chat' section)
For Anger Management: there is a forum section for anger management as well
We don't have a guide just yet specifically for anger management, but there is one for managing your emotions
And if you wanted to look for listeners, you can even filter them by topic to make sure you're only seeing ones that have said they're good with taking chats on the specific topic
(under 'browse listeners' then click 'more filters' to see more options)
I hope all of that helps!
