Milly isn't eating again!! Only 6 weeks since last episode of stasis :-( Please help

Just got home to find that Milly won't eat again. We have the following medicine at home: Zantac, Emprid, Metacam, Infracol. Should we start administering medicine? Please help. She was fine when we went out at 8. 2.5 hours later she's not eating So stressed.

I am not at all experienced in these matters, but didn't want to read and run and leave you with no replies. How is Milly now? I hope she is feeling better xx
