I have found a way to happiness, but it is impractical…?

I’ve had chronic depression and fatigue associated with multiple sclerosis. I’ve found a way to cope: Making my home the epitome of comfortable. see, when my mood is down, and I’m feeling too low & too tired to clean my house, it just builds on itself. That cycle results in even worse levels of depression. But when my home is clean and perfectly decorated- it feels soooo cozy. I dont care as much if that not feeling well, I just curl up in my cozy room with a cup of tea and relax, happily. It makes all the difference to have everything in my home perfect. I really don’t ever get that depressed then.

Yes, I also have always taken antidepressants, but of the lifestyle changes I’ve made- this is the one that seems to be a dealbreaker when it comes to whether the depression is more than I can handle or not.

But I’m ready to marry my boyfriend of 9 years soon. I love him very much, & I have decided to go ahead with moving in with him, and already signed a lease with him.

Its going to be me, him, and his 2 cats cramped into a tiny place. I mentioned I have multiple sclerosis- I don’t feel like cleaning up after all of them. He is sweet and I think he will try to be clean, but lets just say it doesn’t come naturally to him, so who knows. Plus, it’ll be all of us packed in there, in a small place. My furniture I used before was shared with former roommates, & we don’t have any now. (we are pretty broke right now). I don’t know how to cope now. my method I had of maintaining happiness is going to be hard to use now.

I seriously would just stay single forever, so I could always be free to not be depressed, no matter how lousy I felt physically. If my home is a happy looking place- I’m happy. But this guy is worth it to me, worth giving up my happiness. Plus he needs me, he has health problems of his own (glaucoma) and all his $ goes into it. He can’t afford his rent and taking care of his health both. so, we need to co-habitate in a 1 bedroom small apartment to help him. But he doesnt understand why it is so hard for me to give up my way of living. He thinks I am selfish. please tell me how to not resent him for taking my happiness away.
