Help for getting my mom a heart surgery

My mother collapsed due to heart failure on 13th of December and my little brother who was there with her panicked, called an ambulance. When they rushed to the ER, she was told she'll need a surgery for not having enough rhythm of heartbeat. But, the doctors were already scheduled for another surgeries she needed to put on a waitlist. 

We lost our dad 2 years ago, my mom is a single mother who's trying to work as much as she can to make our lives better. According to her doctors, she'll need a pacemaker device in her chest to keep her heart beating and she has insurance covering portion of the cost and leaving us with a bill of $60,000. 

In this hard time, every dollar donated will help lessen the burden on us and our family appreciate all of your love and support.
