Panic disorder

Forgot to take my medication and had a panic attack. Anyone disassociate with there panic attacks? Not sure if thats what its called but last night I had a bad panic attack and everything felt fake and I didn't feel connected. I had to ground myself.. I looked at old photos,Squeezed my hands, thought of nice memories. The photos really helped. Ive had it before with my panic attacks just never realized that's what it was. I also heard holding and ice cube in your hand can help.. Really hard for me to remember what I was feeling that made me think I was dying and that nothing was real... It was almost like amnesia but I had all my memory. Just nothing felt like it looked right. Everything felt off/wrong Glad I could talk myself down without bugging someone to help me tho. I haven't ever been able to do that so I guess I'm proud of myself...
