Passing away...

Hi everyone. Sadly my Ramulus artemis stick insect is at the end of her life. She is about 13 months old and can't climb anymore as she's weak and has lost 2 limbs within a few days. So I'm unfortunately wondering if I should let her pass naturally or if I should euthanize her... I don't want her to struggle and suffer so I'm not sure. Any advice is helpful!
