my cat is sicker than I thought

So, kitty went to the vet today. A traumatic experience for everyone involved, trust me. She did her usual puking, hyperventilating, ripping her nails apart, speaking in tongues and all that.. but it turns out that I got a bit of bad news. Kitty has a heart murmur. I do too. Kitty has unexplainable spots in her chest, which, shown on an x-ray, are bright and have never been seen before- by *any* of the vets. Kitty has a fast heartbeat. Again, another scenerio with which I am familiar. However, her heart valves are wearing out because she "strains" herself on top of already pushing her heart to do double duty. That means she is going to die sooner. Kitty also likely has either diabetes or a thyroid problem. She had blood taken, results for that are pending. She went in for possible constipation. I'm sad.
