Your health care provider can only help you if you tell the truth. She would not ask the question if she didn't already think that there was a probability. Get the help you need, when you need it. There's no shame in a hospital stay. You would not deny yourself health care if you had a broken leg, so don't deny yourself the care you need if you feel suicidal. The people that care for you in the hospital enjoy their jobs because they are improving the quality of life of people when they need it most. It's very satisfying work, I hear. If you need to go to the hospital, you will be walking into loving arms. Be honest with them to get the best care and get it quicker.
