High anxiety day

My husband is having stomach issues right now and hes not sure whats going on. He thinks its more than just built up gas. His father recently passed from prostate cancer and he is afraid he might have somehting. His dad went into the hospital for stomach issues and found out he had stage 4 cancer with no treatent that could help.His father passed 3 weeks later. He rode his bike over 12 miles just a couple weeks earlier. I'm so scared for his test results to show something more than just a bad diet and stress. He stresses about money, bills, work and our 14 year old child. I'm tryng to be as calm as possible to keep him calm but I'm freaked out. His blood results online last night just showed he could be pre diabetic. But he can lower that number by cutting out chicken sandwiches from Mcdonalds and eating healthier. I think its just a bad diet. At least I'm praying its just bad diet and not exercising. I havn't had bad anxiety in a few weeks and last night spiked. I just told him I was tired and anxious from a long day. Then this morning I talked him into eating a banana with his fruit salad and he tried to hand me a sharp knife to cut it. I told him I needed a butter knife to cut it like my mom used to and as I was cutting it, I started crying because all I could see was my mom cutting bananas for my sandwich when I was younger. I miss her so much. I needed to hold back because I didnt want to add anything moe to my husband. I love him very much and I dont want anything to happen to him. I know he has done the same for me. I lost my mom to cancer also in the same way. She went to the hospital for chest issues and was told she had lung cancer. She passed 6 weeks later. I was only 19.It hit me so hard this morning. I'm worried about my husband and I miss my parents so much. Its a very hard day today. I know its not about me but I feel very overwelmed. Usually I'm good under stress but today I cant today.
