I'm running out of time

I can't live like this everyday is like literal hell for me and worst of all I don't have a sure method. Days ago I learned about shallow water blackout and that gave me so much comfort I was feeling all fine knowing I'm able to end it anytime but then agin realized that's not possible to do in cold freezing water. I don't know what to do. Please someone talk to me
What does it mean when you say you are running out of time? Is there a significant date that's important to you for some reason.
Look I get that everything is in a state of flux for you but if you can take a step back and think this through. I don't know if you have asked for help or what the situation is but I can tell you that ctb should be a last resort and is seldom a viable solution when it's rushed.
Some (well me anyway) are able to calm down by thinking and planning ctb carefully, it brings a calmness to a mind that is in conflict with itself, in the meantime I am trying to get help, there is nothing to lose by this.
Try not to do anything impulsive, I can feel how distressed you are, keep talking to us
