I have been having excruciating chest pains that only happen at night and would wake me up balling my eyes out (im good with pain)

well I finally went to the hospital and found out I have gallstones. I am in an emotional funk since then. the doctor told me to change my diet so I won't need the surgery while I'm pregnant so we went shopping and got all new food and stuff for me to eat. I know it's a good thing im changing my diet before the baby gets here but I have never had restrictions on food always been healthy (except finding cancer cells) and never had a surgery. so I feel like everything fell apart so fast! :(
