i had terrible paranoia and anxiety about death. i was a very low bottom drunk so it was probably very well founded however scary it was.
it's just apart of the withdrawal process though. even though the shakes are usually gone at this point, the brain continues to detox for many months and this is just one more thing to cross off your list of things you never wanna do again.
i gotta say the paranoia stuck around until the 2-3 month. after that, i really started to even out mood wise.
I also had OCD as mentioned by another poster but the longer i stayed sober, the more the OCD went away.
