First, my condolences. I know how you feel. I lost my BP 7 months ago and it still hurts. Second, your question, "Is it my fault?" Your actions were reasonable, responsible and loving. I don't think you should blame yourself. This experience, painful as it is, will only make you a better keeper. I think another herp would be lucky to have you, so I hope you won't let this deter you from continuing in the hobby.
