Jo,your friend is probably young and healthy and not able to fully understand what you are going through.She sounds like she might be abit jealous of your new friendship with Sam.I guess you have to think how important is this friend in your life at the moment.If she is then you'll overlook her shortcomings and "make up".If she's abit toxic and stressing you out then it won't hurt to keep your distance for awhile.Congrats on finishing chemo-you are soooo brave to go through that at your age.After chemo,radiation will seem like a picnic!!
