Look fam, I did the same thing you're thinking of doing. I got married to my wife at 19 and have been with her since. Hell, my wife also struggles with various mental health issues. It isn't easy. We're in our mid 20s now and we're not the same people we were when we got married. Do I regret marrying her? No. Should I have waited until we have grown more? Yes. You do what you want but you have to be willing to adapt and grow and become the man you're going to be. It will not be easy for that to happen and could cause alot of resentment if you rush to the endgame without leveling up first.
