I do agree that hanging is probably the most accessible option for ctb in the UK, and of course it's sad how suicide has to be so difficult, I get that so many have succeeded with hanging but it sounds like a horrible and risky method to me. But I guess that the option is always there and it's always possible to go through with it, as so many have succeeded after all like I said.
Your feelings of wishing to leave this world are understandable, to me it's so cruel to restrict the more desirable and peaceful suicide methods meaning that we potentially have to struggle so much in finally leaving this world. The unfortunate reality is that the world that we exist in is so focused on prolonging suffering rather than respecting people's decisions to leave and I hate how things are this way.
