I'm kinda new around here (been lurking for months), but I just want to add:
If you were taking prescription meds for depression or anxiety and you stopped them abruptly when you started the IP, some of your panic/anxiety/etc can definitely be related to withdrawal symptoms from the psycho-pharmaceuticals.
If that's the case, just to to Google, type in the name of your med and the word "withdrawal"...and read the horror stories (along with the list of symptoms, etc).
