Is it weird that I feel relief instead of grief?

my soul dog passed on Thursday.

She had been sick since December. in December she was diagnosed with a bladder infection and bladder stones.

later in the month she needed emergency bladder surgery.

on 1/18 she was diagnosed with ITP (immune mediated thrombocytopenia) and hospitalized. she came home and after that she was peeing every hour around the clock. it turned out the meds increased her liver enzymes and she had low urine concentration.

we ended up in the emergency vet every week and a half on average and she had an ITP relapse two weeks ago. she was hospitalized again.

she came home and wasn't doing well. her balance was off (she'd try to jump on the couch or bed and fall on her back, I HATED it), she was lethargic, she was peeing every hour and we went out every hour around the clock, her front legs would shake and she had labored breathing.

my primary vet suspected her abdomen was filling with fluid and she kept giving me whale eyes like she was super uncomfortable and asking for help.

after spending 30k on surgery, hospitalizations, and follow up, I scheduled her for euthanasia.

she was euthanized last Thursday and the first two days I was a wreck, but the last three days I've felt nothing but relief.

this was my soul dog for God's sake! is something wrong with me? I feel like a psychopath.
