Worst day of my Life!!!

Last night I went to my boyfriend's house to spend the evening with him and when I got home my dog Brandy had vomited up a plastic bag. Wondering where she had got it from and why in the heck she would eat a plastic bag. My mother and I both work at the vet's office here in Red Bud, so right away we were concerned. My dog Brandy will be 16 years old in June, I have had her ever since she was born, so she is means the world to me. Right away I gave her some food to see if she would eat, after vomiting, but she would only drink water. This morning when I woke up she had vomited some more, so I called my mother at work and she told me to bring her up and they would palpate her stomach to see if they could feel anything and possibly take x-rays to see if anything shows up. I hated to leave her, but they told me before I left they would call me right away if anything changed, to where I needed to be there right away. If they do see something they may have to do surgery, because otherwise it can cause a twisted stomach which would kill her instantly. I can not wait to get out of class to go see her. Although it sounds weird she has been my best friend through everything, she is the one that I can talk to and I know she will not tell anyone. When I am crying she will lay her head on my lap and look up at me with her big brown eyes, which instantly puts a smile on my face and lets me know everything will be alright.
