I've read a bunch of those posts you're talking about, and have a bit of advice for you about it:

You do threaten your life, and you don't seem to understand that others find that very, very triggering. That leaves everyone feeling worse after the interaction, which isn't what anyone wants.

You don't have to understand [b]why[/] others find the topic of suicide so triggering, but if you remember that it is true, and avoid that topic, I think you'll do much better. Also, when you write that you are going to kill yourself, I think you maybe are trying to convey that you're in pain. It's OK to say that you're in pain, without taking it that step further. You can say, "I don't know why I hurt so much." Others will understand that, and are likely to offer support, rather than getting into the sorts of muddles that have been resulting lately.

I'm sorry that you're in pain, and I'm very sorry that you're so confused by all this. Keep in mind that it doesn't have to be nearly as hard to get along as you seem to think. You do get support at The Other Place you're discussing, but you also seem to jump in without thinking. I hope your new meds help with all that.

Good luck.
