Please help my Lilo

My poor girl has been urinating blood and has a chronic double ear infection. She was diagnosed back in April with crystals in her urine so vet put her on antibiotics and a special diet to reduce the crystals. Seemed to be working for a while but now we need to do more lab work to see what’s going on. I lost my job few months ago so things have been tight otherwise I wouldn’t ask my friends but it’s just one of those hurtles life throws at you. Lilo is my best friend, she’s truly the sweetest girl in the world and I wish it was myself who was in this situation and not her. Any amount would help and I’d be incredibly thankful for. Prayers are welcomed as well.
