medical debt expenses

Hi, my name is Breanna. I am a 22-year-old girl who was raised by my wonderful grandparents. We were never rich by any means, but we got by. I've worked numerous jobs since the age of 16, from fast food to customer service, to manager positions, but I've never had a clear direction of where I wanted my life to go, or where it was even currently going. I spent a lot of my teenage years either working, or spending time with friends or family. I never truly indulged myself in hobbies or arts that interested me, which is a deep regret of mine. Now that I'm in my twenties, I'm realizing how much time I wasted away, and wish to do so no longer, but sometimes life or different circumstances make that so much easier said than done. 2 years ago, I lost my grandfather to stage 4 lung cancer. They told us that it was likely caused by being on the navy ships during his time in the Korean war. We suffered a large financial burden once he started his radiation and chemotherapy treatments. He passed away not even a year later, regardless. So not only are we left with a massive emotional scar, but also a financial one. Not only from the medical bills, but also the lack of income that was once my grandfathers. Though I have a small waitressing job, it is not nearly enough to truly help her in these times, as well as myself. I understand that some take up multiple jobs, but with my grandmother being 89 as of this year, I have also taken on the role as her caretaker. I would love more than anything to make as much money as I can for the both of us, and I have a desire to go to college, get my own place, help my grandmother with her finances, and be prepared for when it is her time to leave this world... yet it is truly overwhelming, so I have put my pride to the side in an effort to do all these things. I am not one to ask for help, but any amount of help or donations will truly be a blessing for me and my family...
