Hey there,
I'm sorry to hear about your daughter, I'm not sure about the circumstances she is in. But be prepared to be a third wheel and your amusement will gradually increase about that all important 'confidentiality' clause if she is sectioned. Try not to be hostile toward the the MH staff they will not tell you anything and if they do, its only a courtesy and you should be thankful for that. It depends if she went in voluntary or sectioned, the voluntary ones have the run of the show and are allowed many privileges.
Sometimes they can threaten you legally and are allowed to remove your parental rights. Talking to the doctors behind her back, might make her distrust you a little. It depends on her relationship with the doctors and her response to the assessment. Im sorry to hear about the olanazpine, it does have side effects, i wont scare you with that. Lithium is from my experience is ideal. Unfourtantely only with experience can you find the correct dosage and the correct medication, semi-sodium valporate (a mood stabiliser and anti epileptic) has a really hilarious and interesting side effect, it made me loose lots of weight, which I might say I was rather pleased about. Although it did feel like I was extremely hungry all-the-time and I couldn't eat a morsel of food.
Not had any experience with citalopram before. The aim of the game is for both of you to relax, bring her some things like warm socks, slippers and nice Pyjamas. Maintain regular contact, and if i were you i would stay away from the medical side of things, just visit her regularly. Every single day is best once a week is not enough.
Try to get her mind of the assessment and keep bringing those surprises cute little soaps of all shapes and sizes and different colored ones too, shampoo and handwash. Keeping clean will leave her feeling great.
