I thought I was in the clear.

I thought I was in the clear. I had saw a traumatic event over a month ago and ever since then I was having trouble sleeping. I was stuck in fight or flight. I always take a half mg of Ativan and have been doing that for a couple years. ER also gave me hydroxyzine and I’ll take a half of one. About a week ago I was finally starting to get sleep and then this past Tuesday rolls around and I had to be up early for a work meeting and bam I didn’t sleep almost all night. And now I’m back in the insomnia spiral. Wednesday I got some about 5 hours and last night I got maybe 2. I feel like crap. I thought I was getting better but nope. Anyone get insomnia in waves?
