Help Sasha to get well

Hello please help me at least with a SHARE, my name is Sasha I'm a happy and playful cat but I really need your help to get well right now because my human can't afford to start my heart treatment, I was diagnosed with cardiac insufficiency & lungs problems a short time ago, I was taken to the vet (I don't like going there) when my human heard that I've start coughing, the vet gave me few injections but it didn't made me feel better seeing that my human bring me to another vet who diagnosed me with cardiac insufficiency &lungs problems so he said that I need treatment for it, even if the doctor said that he's not sure if I'll get well my human told him to order my treatment but after hearing the price of it (500€) we both realized that we aren't afford it.

I've got those problems cause I've been abandoned when I was few weeks old

now I'm 1 year and 7 month old, I like living please help me to get well
