When you are shaking like that, is it possible to function or be content and think about good things that you're being taken care of and safe?

The most I was shaking was when my heart was beating too fast after starting Prozac. That was when I was like 16-17. My mom drove me to the hospital and I was shaking like crazy in the car. I was up for 3 days.

They gave me a clonazepam and I melted into bed and woke up so relieved.

But that type of panic I could function idk... I'm just trying to distinguish actual panic attacks from psychedelic flashbacks (Which are much worse as if I'm completely mentally retarded)..
