It's been 8-9 weeks since your incident that made your medical issues worse. It is way too soon to commit suicide. Leave here. Come back in a year if you're still in agony and consider things then.
Yes, you have 2 teenagers, you are completely in the wrong for thinking about ctbing this soon. Whatever things happened, it may be in another month or two, you'll be able to stretch in a way to get out of whatever misalignment you have. If you have children, you need to try to be responsible for them as long as you can. This new accident development happened less than 6 months ago.
If you are still in the same agony a year from now and everything is in horrible pain all the time, then it's understandable to think about it then. Also, if you are currently about to be homeless or face something dire, that could possibly make things more understandable, but otherwise, this is way too soon to consider this.
