So my chameleon died

I've only had her for 6 months. Got her surgery over a month ago that was supposed to save her life. After her stitches were removed her health declined. We only found out what was wrong at her second visit to the new vet (in a row) when it was already too late. They found the swollen area by her scar too late. So the surgery may have killed her. 2 weeks I refused to believe anything was terribly wrong, I thought I had 4 more years. So yeah I made the decision to put the sweet lizard down and they gave me her lifeless body. She wasn't a beautiful green anymore. No more googly eyes and grabby hands making her way to perch on my head.
