Hi Pixiedust72. Welcome to Psych Central. I am sorry you are so despondent. That must be a very difficult life situation for you.
This post offers guidance to resources for people who may be in crisis since Psych Central is not a crisis support site. Please refer to the crisis links in this post by DocJohn founder of Psych Central.

In regards to your question about how to get admitted, in US if you want to be admitted to a psych hospital then the normal path of entry is the hospital Emergency Room. If you have someone take you to the ER you will avoid the expense of the copay of an ambulance if you have insurance (about $200) or the cost if you do not $1500.
If you call the police and tell them you are suicidal they will probably have an ambulance take you to the ER and you may incur the charges I mentioned above. If you cannot have someone take you to the hospital, perhaps taxi or Uber or something like that may work.
Hope you get the support you need.
