I, with my various mental heath issues, would like a pet to help. In my head, if I were to get a pet I could help sooth my fucked up head but my parents think otherwise with their “it’s too expensive” and “I don’t think we‘re a pet kind of household” which is obviously wrong. I’ve dogsit for multiple different dogs and have been completely fine doing so in our home. how do i convince my parents to let me get a bunny?
