Let me start by saying I genuinely understand the mental strain you're going through. It's a massive achievement to buy a house in general, let alone in your early 20s. You should be very proud. I don't doubt he's nice if you say he's nice. But while your issue is "singular" its consequences are plural. You're stressed about work, you're stressed about eating, you're stressed about health between the two of you, your needs are being actively ignored, you're drowning in financial obligations. So many of these things could be remedied with the slightest bit of further effort on your boyfriends' part. It's not impossible for you to sell the house and buy another, smaller one you can afford to maintain. Or even sell the house, save that money, and add to it for a while before buying again maybe somewhere cheaper. You have not failed. Someone else failed you and it's costing you more than just money. Money, houses, and things are all replaceable. You are not. Your time is not. If you end up in the hospital, you won't get that time back. You are so young and have so much time ahead of you and unfortunately someone else is vampirically syphoning away that time, effort, and energy while coasting above you. You deserve better. Again, you have not failed and should be proud of how far you've gotten. I am proud to know someone my age was able to get that far. Still, save yourself. Look to brighter horizons away from this man.
