Hello there, I've reached the end of my line and am ready to put a period on a life filled with illness and abject failure. I've decided that Helium suicide with a CPAP mask was the most failsafe way for me and have gone ahead to procure a tank of 99.998% pure helium, a CPAP mask, the tubing that comes with it and after some intense search for the right kind of fittings needed for the outlet over the past three days, I've come across the perfect setup to connect to my CPAP Mask. Everything is all set up and I tested it by turning on the knob on the tank and it hit me with an intense burst of helium that I felt like would be unsustainable for me to breath and make the mask come off. The pressure on it was too great for me and I am not sure what I should do now. I am about to make my first attempt tomorrow morning. I need tips as to what to do with my current setup to make it a successful one. I really do not want to end up failing. I've invested all of my resources into buying this tank and failure means that I don't have any alternatives. Any comments and help will be highly appreciated. Wish me luck <3
I am gonna attach the setup images to this post, please view them and let me know what I can do.
Please check at my messages history, if you can.

I did exactly the same as you and my "fail-proof" method, miserably failed, because one of this:
1) Oxygen contamination of the helium tank
2) Oxygen infiltration inside the mask
3) Excessive helium pressure, caused infiltration around tubes
For my next trial i totally revised the system:
1) I will go with nitrogen, that i got already
2) I will use a two-stage pression regulator, that i got already
3) I will use a diving mask, that i supplied already with proper adaptors for nitrogen tubes
The most important thing is to get a mask that allow exale breathing and inhale only from the gas that fits the mask chamber, any excess of gas should flux out the exhaling pipe, with all the oxygen that the nitrogen will blow away then the regulator will be activated.
Basically, inhale channel should not allow exhale and must pump gas, and exhale channel must not allow inhale, and breathing.
Also firemen masks have this features, but they have two inhale channals, so, one must be sealed or it may pump oxygen with the gas.
I am against the "bag method" because without a proper gas regulator or during inconsciouness, the bag may just "pop" like a balloon, gas pressure has variations and pressure changes quickly with temperature variation due to gas exhalation. SO risk failure is quite high.
Make sure of what you do, because my failed attempt, damaged my vision and my way of walking, also since then my concentration and ability to talk by voice, is quite compromised.
