Help Doubts on planned method – in need of advice

[DeathOfaUnicorn]

I was originally planning to CTB after June, but due to my mental state spiralling further, I've come to the conclusion I have to CTB before June. At first, my plan was to use a helium exit bag – I've been reading about it for some time and I was really interested since it seemed like a peaceful and painless way out, but now that I spend more time browsing this site, I've come to realise I might not be able to use helium.
I would need really expensive equipment, and even if I did buy it, I still live with my parents, both who already know of my suicidal tendencies, and would question it.

I'm a bit stuck, because I don't wanna use any firearms, jump off buildings, drown, overdose, or hang myself, but I'm running out of choices and time.

If anyone knows any similar method to the exit bag, or any affordable alternative, please let me know. I'm growing desperate

Any inert gas method requires equipment and money. You ruled out 5 other methods. The only legitimate option left is either CO or SN. But, that doesn't sound like it would work for you either, since it requires some equipment, some monetary investment (not as much as inert gas), plus, as you said, you live at home. OD's of various drugs frequently fail. You'd have to have SN shipped to your home, which probably isn't a good idea, and it takes some other meds, which can be hard to get, to increase its efficacy. Don't know of any other legitimate ways.
