My pet is dying

My cat is dying. Last time he visited the vet, he had a seizure at the practice. He is a old cat. His age is a little more than 18 years. He is dying now. It started with falls but he can't move at all and he lost control of some muscles for now. I am desperate. He is dying. My all time best friend is dying. He was 2 when he was abandoned. He is old now. I am waiting for 20 years to get my pet. He will die before I can get a new one. I never thought he would die. He was perfectly fine. He is biting his own leg. I am at the end of my rope. I don't know if I can be good again. Can I?<br><br>I will never see you again old buddy. It was fun with you. I can't forget you off my mind. Your pace is much different than mine. I wish I could help you.
