confused sad heart defect and possible di George's

Hi I'm 22weeks tomorrow last Thursday I had my fetal heart scan and truncus arteriosus was confirmed but had to have amniocentesis for di George's 😪🥀 the doctors seem to be doom and gloom but I've been reading up and some people live normal lives or some symptoms. The consultant and my fiancé and family are for termination if positive for di George's but I couldn't do it I don't think. We are effectively giving up on a baby who could be ok apart from the heart problems 85% chance that she will survive heart surgery and we have been given a 30-40% chance of di George's positive dies anyone have any advice or hope?
