How were the softer patients bullied?

Let me rephrase that because bullying makes it sound like it was intentional, which it truly wasn't. Depending on how the illness manifests itself and the severity of it, patients will behave differently. Some will be more aggressive than others. Many in the ward had multiple diagnoses too. The more aggressive patients would often scream at the "softer" patients. Some would reserve tables and refuse to let anyone sit at their spot. Other patients would often forget about the "reserved spot", sit there, and get screamed at. Many of the milder patients were the elderly so it was painful to see.

No curtain between the beds?

No curtains. Just beds next to each other.

What were those not psychotic suffering from?

There were only 3 of us. One woman had bipolar (without psychosis), the other one had depression and anger issues.

Why were they not put in another ward?

We should have been put in another ward. It's well documented that you can't group patients with different mental illnesses together. It will make them worse.

What do you mean by "ration the water"? You only got a cup during water time, couldn't press the bell to ask for more? Maybe the no water bottle rule is because they don't want you all to throw it at others.

Yeah, I think they don't allow personal items because just about anything can be used as a weapon. You can drink water during mealtimes, but for the rest of the day, you're stuck in the ward and you have to go up to the nurse and ask for water. They give you a small cup, and no more. You can't request for more, they get pissed off. Maybe they ration it so that patients won't go to the toilet.
