Agreeing with who said you should make a move and get some papers on your condition. Maybe an early retirement? Then you can work out your way with less stress, doing something you don't rely on for a living but allows you to earn something.

This thought causes me a lot of anxiety, but truth is our SOs aren't supposed to take everything we might possibly come with and we know how easy is to slip in a never-ending circle of complaint vs. complaint. Your SO knows your condition, but he also expects you to thrive here and there like any other partner, not only for the bills and for the money, but because he knows it'll give you fullfilment, joy, sensation of accomplishing something, idk.

If he is not being unsupportive, unfair or negligent with your mental illness, then it's up to you to break the circle. Do what it takes to make this situation better without exposing yourself to a great amount of anxiety, don't lean on him that much to the point of not making your own decisions, it's indeed too much pressure.
