Buy exit bag or SN

[readytogonow!]

Hi everyone!
I've been looking into a few methods to ctb.
Initially, I was going for the exit bag method and acquired oven bags, duct tape, a small 99.99% helium tank, tubing, etc. I then realized I would need a lot bigger helium tank which I'm unable to get my hands on since I live with other people.

I also attempted to hang myself but could not get myself to make the jump. I tried for so long to get myself to do it but I just couldn't. Too scared of the pain and not being successful.

The easiest would be to swallow a bunch of pills but I also know that this is the worst way to ctb.
Lowest rate of mortality.
Highest chance of survival with long term disabilities.
Also, painful and takes a long time.

For the SN method, where are people getting SN from?
I saw some forums mentioning someone named "A".
I'm in the US. Does anyone have that contact?
Oh and also is there anyone I can buy an exit bag from? Hoping that eventually I can get the bigger tank but the other issue is with the bag. I've looked at the instructions but still don't understand how to make the bag the right way

For me it will be both.
Why not combine methods?

The most common source is DMC. I was eventually able to find it by following people's hints on here. The one that finally helped me get to it was using a search engine that starts with "Y" and is less commonly known in the US.

How would you combine them?

Puking in the exit bag would be nasty as fuck and could interfere with the asphyxiation. If you're not too worried about that maybe it could work out.
