I will miss my Chelsea T_T

As I wrote about earlier.. almost 2 months ago I found out Chelsea had renal failure. It had gotten worse and worse over the last two months and within the past couple weeks she had started to meow like she hadn't before, almost a screech like she was in pain and crying out, whether I was around her or not. Yesterday, she also wasn't able to help it but she peed on my floor in my room which she never used to do. She ran out like she knew she was doing something wrong but couldn't help it... My family and I decided that it was time to put Chelsea down and stop her suffering.. So almost 5 hours ago, that's what happened. My sister took her to the vet at noon... I know it must have been hard to be there...  and I have been thinking of it all day. Over the past 12 years, since I was just 6, she's been my little friend and has kept me company almost every night. She has brought me comfort when I was feeling lonely or angry. I've cried a lot.. she was my little cuddle buddy and felt like a part of the family and now she's gone, and she'll be greatly missed =*(
