What country are you in? I've been to a psychiatric hospital 7 times and it was always at least ok. Just a bit boring sometimes. But often I liked it. The staff can be caring, the food is good and regular, and you can meet like minded people, find friends, even a partner like I did! Plus they're there to help you feel better. It's a nice diversion.
They'll hospitalise you only if they think you're an imminent danger to yourself or others. If they believe you could seriously harm yourself soon then they'll want to hospitalise you. If you want help but don't want to be hospitalised you could tell them that you have regular suicidal thoughts but either that there's something stopping you like not wanting to hurt family, or that you haven't had any plans on how to hurt yourself, eg cos you're too scared to jump off a building or that there are no safe, reliable ways to die so you don't want to try.
Plety of people hear voices and don't get hospitalised, even if the voices are telling you to do bad things. They make a judgement about what your actions are likely to include. But maybe hospitalisation wouldn't be so bad? It really depends what country you're in as to what the experience would be like. In the USA and third world countries it's not good - but might still be advisable? In the UK and many European countries it's much much better. I'd even ask to be admitted under a voluntary basis. If you don't like it, just leave. But wherever you're admitted, if you don't like it and they won't release you, just call a lawyer and have them get you release, under the premise that you're not a danger to yourself or others and have not demonstrated that you are.
