I want to kill my family's dogs

I'm 16, live in England. I can't move out due to disability.

When I was 3, my mum got 2 jack russel-pug crosses. When I was 7, she got a chihuahua and a poaching. When I was 13, she got a pug.

I hate those animals. We're not emotionally equipped to care for this many of them. The jack Russell-pugs are shut in the kitchen all day, they shit and piss all over it and they rip up any bed they're given.

The other 3 piss all over the house, it stinks, everything stinks.

They park at everything, we can't leave the house without them barking.

The chihuahua poos up walls.

That's not even everything.

They're driving me insane. I've tried talking to my mum about rehoming them or looking for a shelter. My mum doesn't want to.

I've had these thoughts for ages now, but I dont even feel bad for having them anymore. I want to kill those things. I've thought about how to do it. I've thought about how to kill them, how to get ready of them after.

I think I'm going mad, I want those dogs dead.
