Has anyone else felt like this?

Basically, when i was younger at the very least i had to have been about 4 yrs old… yes i remember that far back…. I remember having this deep uneasy feeling ( best way i can describe it ) is a feeling of ( not belonging ) ….. its a feeling that i don’t get that often and it hits me all of sudden…. I start crying when i get that feeling.
It fucks with me. Bad. Im now 25….
Has anyone else felt like this ? What do you do to cope with it?
