How old are you and how many kids do you have?

Strangely enough, the oldest and youngest, both boys, share a birthday. It gets interesting at times.

Aw, here you go kiddo, hell, have two! (you) (you)

Be honest and open, either with your spouse or a therapist - sounds like you've bottled up stuff for a lifetime, not healthy. Once you've uncorked all this, you may find you have a different perspective.
All the best, user.

12 years of anger and counting, mate. I've already made it clear that I'm essentially going on strike soon, becoming a bum

She owes me a decade and by God I'll extract it from her.

Silly user, she doesn't owe you anything - you are the one allowing the anger to fester, never telling her how you feel. Just gritting your teeth and staying silent will not help any situation.
If you are unhappy and angry with her, perhaps telling her why would be a good idea? To get it out of your system and to perhaps find yourself again?
You can do it, user, best of luck.

I am nine years old.

I've already made it clear how I feel and she acknowledges my extreme sacrifice for her but nothing can be done in the short-term.

I've also seen a therapist a couple of times, but it didn't help, since they too acknowledged my sacrifice but had no solutions.
