You are not alone and it is going to be okay. If you have the ability to recognize shit still then it's okay. well, maybe not okay, but you are still with us. And don'tm think that you are the only one who questions reality. I do too. my doc gets worried about me because I get the floaty weird feeling alot when I am driving. He said it is just because the stress of awareness while driving brings on the dissociative feelings. so I pull over now and try to connect by touching the car hood (it's hot) or if there is grass by feeling it, etc.
Just try to get different nerves firing to reconnect . in any situation....not just driving.
