Heart Surgery for my Sister

So many of you may know my sister and I'm sure some of you don't.
For those that do, you know she's the most loving, amazing mom, friend, sister and daughter. She's constantly working her butt of to be the best for her kiddos.
Recently she was hit with some pretty harsh news and has to have heart surgery. Mind you, she just turned 31.
Being a single parent to these 2 beautiful kiddos, that is the last thing she ever expected. Heart issues run in my family but none of us expected it to happen.
She was just told her will have to have just under $1500 up front for her surgery in just a few days as well as rent a few days later. So, I would like to try to raise some money to help her out so she can be happy and healthy for her kids!
Asking for help is the last thing she will do, however I know she won't be able to work for some time.
If you can donate anything, it would be much appreciated
