Panic disorder vent

I'm not sure if everyone has the same symptoms with panic disorders. I honestly only know how its making me feel. For the last few months I've had this feeling in my chest, like I'm standing at the foot of a cliff .

My last attack, I legitimately thought I was dying. I felt alone in this world like I couldn't depend on anyone to save me in time- not that I could've given a warning due to not being able to speak express my feelings. I passed gas through both ends, and peed, at the same time like my bowls were releasing. (At least at the moment it's what I was mentally thinking) ive had mental disorders growing up, PTSD, BPD, ect. I've never had anything this intensely psychological. Just wondering if maybe someone could help explain what's happening ?

Im generally scared to speak with a counselor due to being told I'm flat out crazy.

TIA ❤
