hello, i'm scary of the health of my dad. He has his retirement soon, and he's going to make a large farewell party. He had a lot of stress during the last weeks, but now it's going really crazy, he didn't sleep nearly anything the last 1-2 days, and now he gots hallucinations (he dond't know where he is, or how late it is). Finally we got him to sleep (since 30 min). Do i have to worry? or will be everything okay when he wakes up? please help me. dates about him: 56 years old, ~90kg, 180cm, non-smoker,
