Good luck to you. My the Angles sing at your mom's side. My Mom surived cancer a few times (first at 70). It was like yesterdaysitting in all the Doctor's office. Not knowing and keeping our finger crossed. Just going on HOPE. My Mom was my best friend too. SHe suddenly passed in March. I life will never be the same. I have memories of your love. Cancer beat my Dad 40 years agao. Cancer has been a part of my life for my whole life. take you mom and hug here. SChool can always wait. That decision is up to you. I would do ANY THING to have my Mom back. I cry every night and so does my brother. He lives in a Nursing home because he suffered a stroke last year. My Mom went daily. Just take it one day at a time. I use to plan every day out. No more. God bless you.
