We csnnot recomend ctb methods, it's sgainst forum policy
I understand it may be difficult to acquire suicide materials when you don't have money for it
But I'll instead tell you what not to use in your home:
Knives: cutting rarely works and cutting or stabbing where it matters is way too painful and you wouldn't be able to do it
Cleaning products: too painful, may not work, terrible sude effects if you survive
Electricity from a house wall socket: too painful, would take ages to kill you
Starvation or dehydration: your instincts would stop you and it would be torture
Medicines: most don't kill you at all, and even the few that do, will leave side effects if they don't work
Plastic bags over the head: it will only work if you make sure nothing will rip it open, not even yourself, and there are no holes for air to get in
Fire: worst pain possible
Drowning: añso very painful and anywhere you could drown at home would be easy for you to give up once survival instinct kicks in
I understand that didn't leave much option other than msybe ropes, stronger meds or firesrms but I am sure that by studying this forum you will find a method that brings you peace and comfort and is within your reach
