Just checking if other people experience the same thing as me and I'm not actually psychotic lol....

I get these "episodes" where my thoughts are racing and I feel really "distanced" from my surroundings -- I feel dizzy, can't process things properly (sounds are loud, I can't respond quickly, lights are super bright, feeling of sensory overload almost). My thoughts don't always make sense either-- a bunch of assumptions and "what ifs", and I start panicking cuz I'm afraid I will snap at any moment. I get really afraid I'm psychotic or experiencing some type of mania because my thoughts are so ridiculous. Anyone else?
