How to feel

Hi I am new to this forum and been to Drs today to talk about some symptoms I've been having and has requested a ca125 blood test and ultrasound I know it's not a positive result or anything as the test hasn't even  been done yet but I'm so confused my emotions are all over the place and don't know how or what to feel I know I should be positive till any test results come back but how do you I just keep thinking about family I may leave behind I am trying not to be selfish as there is always someone worse off and my situation just seems irrelevant atm but can't help it  xx I have five children and had fibroids about ten years ago and very heavy painful periods and have been sterilised
