Honestly OP, if there is any way of keeping yourself safe at home, you do NOT want to go into hospital. People think its somewhere you go to get well, that there will be therapy and support and they can just rest and get well. It isn't like that. It's scarcely more than a holding area.
You don't get any more therapy than you would aa an outpatient and you certainly can't rest. The lights are on all night, the other patients scream and cry all night, some take your things or are violent. There is no privacy even in the toilet. If you are considered a suicide risk, they will literally watch you take a shit.
The nurses are stressed and understaffed. If you persist in self harming or become agitated, you are sedated or restrained so that you cannot harm yourself.
They will try you on different medications. You do not have a say in this. If you refuse it will be given against your will.
This was over a decade ago and I doubt these wards have improved since, given the chronic underfunding and mental health crisis.
By all means, ask OP but know what you are asking for.
