@Drew944 I think you need to just take a deep breath and not be so scared. I am sure your cardio has you monitored for the rate the aneurysm is growing and that is the critical issue. If your aneurysm is as slow growing as mine is, it may be 20 + years or more before you need surgical repair. And by then, they may have an entirely different way of repairing it.

I suggest you talk to your cardio about how fast this is growing and knowing it is not growing at a fast rate might give you some peace of mind. I am sure your cardio has suggested limiting how much you lift and that must be tough when you have such little children. But you can sit and they can crawl into your lap and you can have the same cuddling without the lifting. When necessary, I do lift things that perhaps I shouldn't but so far, the aneurysm is hardly growing at all. I have been warned to NEVER shovel snow so I don't and I don't do any work/exercise outside in the cold of winter.

Think positively. Knowing you have this is better than having it and not knowing it is there. I understand your fear and how devastated you must feel but don't let your fear steal your enjoyment of life. I wish you well.
