Hi! My son is 11 months old and is due to go to Leeds on Sunday for open heart surgery on the Monday morning he has a large vsd what was diagnosed at 6 weeks old after hearing a heart murmur he had scans and also found he has teralogy of fallot. I'm absolutely crapping myself about his surgery its tearing me apart I just keep fearing the worst and I dont know what to do. I cant bare the thought of losing my precious little boy I honestly just feel like I'm going insane I'm having nightmares and all sorts it's on my mind 24/7. Has anyone had the same thing with there children and if so please let me know what to expect and what the outcome was xx
