I hope all of this sorts itself out funkmaster.
I’ll never forget when my son, at 10 days old, was diagnosed with CHD and severe reflux. He was due to have open heart surgery at approx. 1 year old but his heart began to fail when he was five month old. It was a long 5 months, dropper-feeding him, watching him throw up 75% of his already tiny milk intake and struggling to gain any weight and miss his milestones.
Both my wife and I would have good times and bad times. One feeling positive and supporting the other and then the roles reversing. Other things that helped were having time to ourselves. An occasional poker night for me, manicures etc for the wife.
Our son, now 2, is thriving and besides the big scar on his chest, has no long term issues.
We got through it together and as other people have suggested, now look back on it as a shitty time but one that makes us appreciate what we do have. I hope you can say the same, sooner rather than later.
