(((((Kari,))))) here's hug for you. It is so draining and frightening to see your child in this condition. Sorry you had to deal with it. Sounds like your son and mine are very much alike.
We had a recent situation with my son being very disoriented, agitated and seeing things that weren't there. He was having DTs due to suddenly going cold turkey from vodka. Long story short, he ended up in the hospital for 5 days of detox. It was very scary for me to see him in such an awful state.
I hope your son gets a good evaluation and pursues the recovery the facility will either offer or recommend. Stay strong and know we are listening.
