Panic attack making me question reality, making my gf’s face look wrong

My girlfriend’s face looks…wrong. Please help.

Want to start this off with the fact that I’ve never had anything like this happen to me before. Ive had hallucinations maybe once before, and it was just seeing bees around everywhere. But this is so fucking terrifying and I dont know what to do.

This started last night when I had a really really bad dissociative event. Was spacing out, I couldnt focus my eyes, i could listen and respond but everything felt…distant I guess. I…couldnt tell if it was real. If i was real. If she was. My girlfriend helped me through it, and for a split second, when I finally looked back at her face, it just looked so wrong. Like her eyes were in the wrong place and her mouth was all messed up.

I started crying even harder. I was so scared. I dont know I felt trapped. Like she wasnt my real girlfriend. Like it was something pretending to be her. It happened a second time later that night, but it looked wrong in a different way. I was finally able to calm down by just looking at her face, and having her reassure me that She and I were real and safe.

Ive been mostly okay today. Things have felt the way they do after big panic attacks. Big comedowns. Ive just been kinda shielded/numb. But when we started to go to bed again, it just barely happened. It was like her smile was bigger I guess? More exaggerated? Kinda like the people from the horror movie smile, but a bit less exaggerated. But it’s always only for a split second. Like im catching a thing right before it changes back into my girlfriend.

Please help me. I’m so fucking terrified and I just want my real girlfriend. I want this shit to fucking stop. I feel crazy. I just want my girlfriend. I love her so much. Please. I’m 19, dont take any meds, have been completely sober. Only thing that might have been affecting this is I haven’t slept well the past week.
