When someone is brought into a hospital by the police, the doctor may fill out a form called, "application by physician for psychiatric assessment". This means you can be held involuntarily for up to 72 hours. The psychiatrist always has to evaluate the person before this form is approved, however, the presence of police bringing someone in implies the person is a danger to themselves, others, unable to care for themselves and so forth.

For the part in bold: the psychiatrist evaluated you and felt that due to the behaviour you were displaying, you met the criteria of involuntary admission. The only way you can show you were illegally held is if you can show the psychiatrist's evaluation was incorrect, although your evidence for this is greatly strengthened by other psychiatrists.

For the part not in bold: for all intensive purposes, your therapist was deemed irrelevant to the psychiatrist's evaluation of whether you should be involuntarily admitted. As for her not being called, it's unfortunate but there's nothing you can do about that.

As cold as this may sound, the psychiatrist and nurses are interested first and foremost with you. They wouldn't be liable because they said they contacted or attempted to contact your friend. That's the best they can be expected to do other than calling Animal Control.

Unfortunately, some doctors will do that, especially if they believe your dosage is too high or in this case, they may have felt your behaviour was partially due to the pain medications. It's pretty common though for a specialist to prescribe 1 dosage and another doctor in a hospital changes it.

That all sounds pretty typical and nothing I wouldn't expect. It doesn't matter if you're admitted in psychiatry or elsewhere, there is immediate concern when a patient is unable or refuses to eat. The food meals aren't controlled by the doctors or nurses, so they can try to order a specific meal for you but it may not be feasible.

Doctors are very busy in hospitals as there usually are only a few of them, a bunch of nurses, possibly some assistants and all the patients. The doctors have to routinely evaluate patients, review with nurses, contact other doctors, review your files (takes longer if another doctor or therapist sends it over) and document everything, all while being called to go elsewhere. It's constant multi-tasking and is very difficult. Personally, I like it when doctors stay with each patient long enough to explain the decision, how they reached it and briefly address any concerns.

Some of this may have been because it's the psychiatric ward and there may be more outbursts there but for something as simple as dimming the lights or getting bed sheets, the staff has very poor communication.

In the hospital where I'm at, I don't, "gang up" with any fellow staff, unless it's clear as day there is a problem that isn't de-escalating. Sometimes patients are aggressive that they are admitted and will try to go as far as attacking. The way I prefer to work is when one nurse is tending to a particular issue, I'll grab the sheets, dim the lights or whatever else, so as to not drag it out longer than it has to be. Afterward, I ask if there's anything else and if not, then I move on to someone else.

I don't know what the situation is for your state but over here, patients are encouraged to bring their own blankets (pillows are provided). It's due to a series of budget cuts, especially to areas that aren't expected to impact staff and patients. Despite this, there still are blankets that can be handed out if need be. If there is a patient that comes from emergency, I don't make a fuss if they don't have a blanket, I'll give them one right away. Sometimes a patient still feels cold despite bringing their own blanket, something is spilled on their blanket, or whatever else. If they need another one, then they'll be provided.
