Pam, there is no reason to leave. There is a big difference in asking for support and asking for a way of killing oneself.
It's not that you can't talk about suicidal feelings, but tell us about it and figure out what you are going to do to make your life better! We aren't here to show you how to end your life. The people here are your friends and want you to have a GREAT life. But you need to supplement the board with some in-person help, and some of your own motivation.
It's like someone saying "woe is me, I'm fat, I'll never lose weight". Well, they COULD, if they were motivated. But without motivation, things will stay the same. I was talking with a friend of mine who is also losing weight, and someone we know mutually had told her she couldn't lose weight, she loves chocolate too much. Well, if you are going to think that, then nothing changes. We each make our own choices.
