Get Scared and Anxious when trying to fall asleep.

Today is day 4, about 86 hours since last drink. Finally got a little more sleep last night but when I'm trying to fall asleep the first time I get so anxious and scared. I start googling DTs and getting worried I'm going to die in my sleep. After I fall asleep the first time it fades and I just kinda drift in and out of sleep for the rest of the night. Anyone else had this?
