R.I.P with respect.
No matter how bad, devastating, soul-crushing and pointless everything seems...it's really not. It's just your perception (which can be changed) and perhaps your immediate surroundings (which can be changed).
Nothing around you is important enough to end your life over, and there is always something to live for, even if you can't see it right now. That's why it's important to talk to someone, to get that perspective.
You can walk and make a totally different life than what you have today, it's far easier than it seems. It's natural to move forward, you actually need to force things to stop.
