A bit too familiar for me to give objective feedback.

I am in the same situation right now, PTSD has been under control -somewhat- for months, now it's like worse than before and I feel like I'm suffocating, helpless, hopeless.

I'm so sorry you're going through this, all I know is that the feeling itself doesn't allow me to think clearly therefore it doesn't matter what I know or do not about myself, it just hurts and that's louder than anything else.

Hope this goes away very soon.
