Gallbladder

Imdue to have my gallbladder removed next week through laparoscopic surgery. I’m terrified that something will go wrong and I will die in theatre or shortly after the operation. I have bad health anxiety and OCD and I’m absolutely driving myself insane with worry. I have a 4 month old baby and I love him so much and I’m so scared that when they put me to sleep I won’t wake up or something will go wrong. Or I’ll have the operation and be fine but then just die from complications. I’m aware how silly this sounds. But I’m quite overweight and 113kg and I’m worried that this will be a factor of complications. Had anybody had gallbladder surgery under anaesthesia and been absolutely fine? Please share your stories if you have any. I’m desperately seeking reassurances.
