I would appreciate anyones help.
Ive been dealing with anxiety, panic, depersonalization, derealization for over a year. But lately it became unbearable, so i would like to know if this is anxiety/panic or something else.
For example today i went to my psychiatrist, and while waiting i started feeling very anxious, i started having existential thoughts ect. When i came in things got even worse. I felt like i literally didnt exist, like i wasnt really there, i felt confused, disorientated, words were repeating over and over again in my head, i felt like voice wasnt my own, my body wasnt mine ect. Not sure how i even responded to my psychiatrist because i barely remember anything since i was so confused. On my way home everything got even worse i thought i had psychosis. I had thoughts like why do i see everything from my eyes, how people looked weird, how can there be so many counciousness, why do i see much of the world, why is everything so big or small, why is everything so far away or so near, where am i supposed to look? Also my eyes were seeing every detail, like my eyes got stuck on one point and it was hard not to look somewhere. I had so many more symptoms i just cant remember them now, since i got home and im better now, still very depressed but better than i was. 
So my question is - what do you guys think, is this anxiety and panic or something more serious? ( also i was seen by multiple psyvhiatrists and everyone said i dont have schizophrenia) so what could it be? Could it be just anxiety? Thanks in advance
