I've been keeping an eye on this topic from afar and learning more, even though my own frog plans are on hold.
I, too have medical issues, JennybugJennifer and know how frustrating and worrying it can be when you take an animal into your home and pour your heart and soul into its care only to learn you may have made a mistake somewhere along the line - especially when other stresses due to your own stuff are present as well!
It's absolutely fine to make mistakes as long as we learn from them, and your questions clearly show that you are willing to - which is fantastic! It can be extremely stressful bringing something new into your life (I remember when I first brought Kaze home - I was up several times a night checking on him and had so many worries it was unbelievable!) but once you've learned more about your indivudual animal and his personality, and have learned more about his species in general that stress will
fade with time.
We just have to endure the initial period of time where our frustrations take over - we'll become stronger for it. Part of me thinks that our animals know the effort we put into their care and they reward us indirectly through their growing bigger and stronger, through their activity and through their general silliness!
I hope you're able to relax soon
