I think one of the main things about getting THROUGH those feelings is a PLAN for distraction. The book The Courage to Heal has a section about this.. and suggests many different types of things, and suggests making a long list for yourself.

On a list put things that are "comfort" items or activities... things that generally help you to feel better.

It might be grab your favorite stuffed animal or team throw/blanket. Have a comfort basket already made up... for snacking, hot bath soak, or activity...

An agreement signed by both you and someone who cares about you... and if IF you feel you have no one, then sign it with the ER nurse or social worker, that you will do xx things when feeling so bad. If you have a predetermined "safe spot" in your home, or somewhere (like a library?) that you can go to when feeling suicidal, that is also a benefit.

Putting the phone numbers for hotlines, and the local help, ER etc are good. My church also has a minster on duty who wears a pager and answers no matter what time (they rotate this around between ministers.) Does your house of worship have such help available?

Along with things to do when you're feeling unsafe, there should also be a list of things you agree with yourself to NOT do. What goes on that list are things that would make an attempt easier... if you are considering running the car in the garage, then you would put on your list that you will not go into the garage at all. If you think you will use medicine, then you state that you will not take more than the normal dose of pills.

Writing things down, dating, signing them with another is useful to read when your thoughts are of only one thing. Often, reading an agreement can prevent further action... something your mind can focus on, and if for no other reason than you said you would give yourself another chance, will stay safe right now.

BTW most of the population has suicidal ideation during their lifetime, this is normal. By realizing that what you are currently going through might be overwhelming you, and not overreacting to that idea, you can continue on...

Stay safe.
