Over feeding baby!

So my daughter is 7 1/2 months old and is not fond of food. I mixed breast milk and a jar of food with some baby oatmeal... It was kind of thick but I thought maybe she'll like it better thicker than I was making it... she did pretty well eating a good portion and did our night routine and put her to bed... I went to check on her because after an hour of sleeping she woke up, I noticed she threw up a good bit of her dinner... she continued to vomit 5 more times and I'm beginning to worry about a virus. I think maybe I just over fed her, which makes me feel horrible, but a virus would be worse. She is now sleeping on my chest with a towel under her and I don't her her tummy rumbling...Anyone ever had an experience like this before or am I just an awful mother who stuffed my poor baby girl sick? I guess it expanded in her belly and it rejected it.. parent fail...
