Morning
Yep, I get that ... when I had OHS #3 I was a bit older than you probably are (born in 1964, 3rd was 2011) and perhaps due to my prior 2 I was more confident I'd wake up.
Perhaps ... but I'm not sure there is much more wisdom I have than just experience and reflection. Now that I've done due diligence and given you what I believe is the best answers I can now go on to say (as you've requested more) that if you want to defer longer then you just do that if you really want to.
So, back at the time I had my second surgery I was actually right in the middle of doing my IT degree, I was about to complete the first stage (which was a diploma) and no matter what happened I could say "I got that" and could then choose to work with that or go on to complete a degree at an allied University. I was very conscious of not leaving anything incomplete.
My surgeon wanted to do the surgery in a short order, I think he wanted to do it in September, but I said that this was exactly going to be the lead up to my exams and I absolutely wanted to finish all of that before the surgery,;it was very important to me. He thought about it for a little while and he said okay here's what we're going to do as soon as you finish your last exam call up the hospital and for your surgery and we'll do the surgery as soon as we have the right valve. This is because I was having a homograph valve put into me (which was a cryopreserved valve) and availability was not like buying an off the shelf product.
He was very clear that he didn't want me to be doing too much exercise too much straining too much anything because my situation with my old valve was the statuses with high and he didn't want ventricular hypertrophy to expand giving me a bad situation in recovery and also for the rest of my life. so in that case I like you deferred even beyond what my surgeon recommended but unlike you my situation was not likely to cause my death by dissection, so I would be very conscious of your aneurysm and make sure that you follow the protocol of frequent measurements and be careful to not lift heavy things strain whatever.
If you go to the gym then I recommend that you cut your weight down to lifeably small amounts not so small that you can't feel it but not so much that you're doing any straining to lift it and do higher repetitions.
During this time before you have your surgery
be aware of every day, be aware of everything and take nothing for granted, be fully alive and be fully present and be fully appreciative of every day.
I have tried to live my life in this way in the last 12 years and even with that as a base reflection on what I am doing then I still find their days when I'm not paying attention and I'm not consciously aware of myself my life and thankful for everything that I have. Especially (in my opinion) you should actually make sure you're thankful for and very aware of your family.
The next thing to remember is that you actually don't have control as a very much, the control that you have over things is actually an illusion. in reality you could get food poisoning you could fall off the gutter in a bad way into the street and get hurt you could have any number of misfortunes befall you. If you get a little bit philosophical every culture philosophy has the view that we really don't have much control over our lives. the reality is that we can choose the things that are before us maybe those choices are wise maybe those choices are emotional maybe those choices are just simply obvious. But if you are going to make a choice you should make a choice as well as you can in the knowledge that no matter what the outcomes are outside of your control.
A personal favourite movie of mine is Shawshank Redemption, in this scene these prisoners were fully present and fully enjoying every mouthful of beer and how they felt in recovery from hard work.

True Happiness is to enjoy the present, without anxious dependence upon the future. Not to amuse ourselves with either hopes or fears, but to rest satisfied with what we have, which is sufficient, for he that is so
wants nothing. (*wants in this instance means simply desires something, like you want a new item when you already have a functional one).

Our emotions are a combination of two elements: an affective movement within the body and a judgement. Suffering arises when we attach judgements to these affective movements that are beyond our control. For example to love someone is within your control, the judgement that this love should be returned and should be so forever is not.
Contrary to popular belief, the goal (of Stoicism)
is not to repress or eliminate the emotions, to become devoid of feelings; the goal is to attach the right judgments to them.
"we are all dying" so don't forget to enjoy the moments you have, savour even the fear (for it too is just an emotion).
Best Wishes
