Recurrent suicidal thinking can be a chronic problem. It still needs to be managed with the help of someone professional. Your 16 year old daughter will need to find another place to live, if you commit suicide. Getting yourself committed may not be what is called for. You are in a better position to know about that than I am. You definitely need to be talking about this with someone involved in your treatment. At the very least, call and make an appointment to see your primary care provider. Go for that appointment and admit that this kind of thinking comes into your mind. There is a reason. Nobody has to know why you are going to see your PCP. It probably isn't fair to put too much responsibility on a 16 years old daughter. I suspect that is what she is afraid of. Can you blame her?

You are important. And your fears and anxieties are real and are exceeding your coping skill. Get help. Also let us know how you are doing. We all care.
