Helllo mubski82, greetings to you too!
'Introduce yourself' is a good forum for new members to start posting but you might get more feedback in content specific forums. As I've already explained to Kevin, Anxiety Zone is divided into different sections/ forums. Find the ones you like and feel free to post or start a new topic. Reading your post I'd recommend 'Specific phobias' or 'Panic disorder' forum but there are always interesting topics in other forums too.
You might also wanna use the search box and type in panic attacks. It should come up with many topics, many stories from people, who are struggling with similar issues.
Beside forums, you are welcome to join the Chat and Anxiety Zone wire, for example.
All the best to you, may you meet many nice people here!
