Thankfully, I managed to make her eat some tuna last night (the only thing she was willing to eat). I mixed it with a bit of water to force her to drink and it worked. After a while her appetite came back. She ate and drank a good amount and was fine afterwards. She got up to eat and drink again in the middle of the night too.
She seems back to normal, happy and playful right now. The bloating has also gone down... but if she restarts feeling unwell today, I'll take her to the vet.

I'm so relieved!
