Is it normal i feel this way

I have been feeling this way on and off for a long time now and it is getting frustrating. I feel a sense of sort of chronic deja vu, as if I am living a life that has already happened and do not control it or myself. This may sound minor but it consumes my thoughts and is very irritating. It sometimes feels like a dream. I am bored with my life and it feels like it is passing me by and there is nothing I can do about it. I feel stuck and have constant brain fog (physical symptoms included). I do not enjoy things like I used to/ get excited for things. I do have a lot of anxiety and I know what depersonalization/derealization is but Im not quite sure if it is that. I have had a few panic attacks and usually experience derealization during and a little while after them, Im afraid one time it will never go away though. My neighborhood and things I see all the time seem somewhat unfamiliar or "off" to me. I feel a constant pressure around my head, get dizzy a lot, my legs go numb, and I lose track of thought often, and get hot flashes (I am young). I feel like I cannot find clarity and am restless in my mind. I question unrealistic conspiracies or scenarios. I am just waiting around for my mind to clear up and for me to feel normal and start feeling like I am living my own, real life, but I am paranoid. Is this nothing? Am I over reacting?
