Panic Attack and Depressive Episode: Coping Mechanism or Something More?

Last night I had a panic attack + depressive episode at once and I had this switch in my mind where I slowly fell into a little space. I do not have DID or a personality disorder, it’s a coping mechanism my mind does under stress sometimes. Though this time was different. I felt small, I went mute, and teary eyed and extremely timid and jumpy. I had jumped onto VRchat with my bf and I tried the best I could to explain what was happening [through writing on a wall with a pen on a world]. I eventually laid onto his chest for a bit and I then forced my mind to revert back to my usual mindset. I just wanted to share this experience and see if anyone else has anything similar.
