I few days ago I mixed chemicals together to create a very very dangerous gas called Hydrogen Sulfide. When I mixed the chemicals there was no reaction so I thought it didn't work and poured it down the bathroom sink 

But later I realized that I could smell rotten eggs in the house (the smell the deadly gas makes), I opened all the windows and took my dogs outside.

I waited in the bathroom for an hour to see if I died or if it was safe before my family got home.

I originally planned on not telling anyone but when I got really close to my sink I could smell Hydrogen Sulfide, I googled it and sometimes it's a problem with the sewers that could've been there before my attempt but I was so scared I'd harm someone, so I told my mom that night and she said its probably fine and thanks for telling her

I don't know If she fully realises how deadly and dangerous what I did was, i feel so bad and even more suicidal.  I could've killed my whole family and myself. I can still kinda smell it but my mom thinks it's just a problem with the pipes.

We're literally moving house next week so I could've or even could still harm the new tenants. I'm so stupid and I know I shouldn't have done it now but I wasnt thinking when i did it because I was so suicidal. I wish I didn't do It, and I can't live with myself knowing I almost killed my family and dogs. I'm just waiting till we move so I can hang myself off the balcony for what I've done.
