Missed Call and now I have to wait

As a follow up to my post about Urgent Care, I saw my PCP on Monday and had an ultrasound this morning before work.
I received a voice mail from my doctor's office alreay and now have to wait until the individual that called me is available.
I am 100% sure I have these gallstones and I know I will need surgery. I have NE's NCL presentation, graduation, and dance show in the latter part of May, my cruise at the end of June and open enrollment somwhere in there. Missing any of NE's milestones for her senior year ARE NOT an option, nor is my cruise, open enrollment well work will have to suffer without me and my counterparts from the aerospace will need to help me out again.
I am upset but not scared. I am upset that I have this and a lot mad at myself. I need to get serious about eating healthy, losing weight and not just sitting at my desk all the time.
I am grateful because last Friday I reached out to a friend MG who had this procedure late last year and she was very helpful in giving me information and encouragement.
I talked to my SIL this morning and as always she was very encouraging and supportive and offered to come stay with me for a few days.
I told my boss and he was positive and told me to remember I have to take care of myself first as I am number 1.
So now I have to wait for my callback that I missed. Oh how did I miss this call - yeah phone was on silent.
