Thinking of you both @MissGremlin @Captain24 and hoping you can both get some extra rest today despite the anxieties and worries about your respective meetings/appointments tomorrow. (And of course the additional major stress of Pix's health @Captain24 )
It would be confusing for Jett too, not knowing where Pixie has gone or why. I'm glad you are there with her though. You mentioned Jett also goes to the vet hospital tomorrow? Or did you mean to your mum whilst you have your appointment? (Sorry, just wanting to clarify as i'm confused lol - which is not a problem for me to be confused though lol)
I hope you can get some rest knowing the Pixie is in as much and safe care as possible, and there is literally nothing more you can do for her currently other than make sure you are as well as possible to then be able to care for her at home again once she is healthy enough for that too. I know it doesnt take away the anxiety and thoughts and fear, but also that focusing on these worries won't help Pix get better either - since you have already acted on getting vet help 🥰.
Is there anything you can take to help calm the thoughts and feelings if they are overwhelming and preventing you from getting some rest whilst she is at the vet hospital?
