I get that you might feel like the serious of your illness is not recognized by other people. Nobody can really know unless they experience something similar themselves.
But also if you live many people under the same roof you all need to adapt to each other and cooperate to get along.
I would try not to think that when one of your family members asks you to adapt it means that they don’t care about you. It’s difficult to live many people under the same roof. I totally get that from personal experience. It’s easy to get on each others nerves, but a lot of it has to do with how we choose to interpit and deal with things in our mind.
But if you have no choice I would just try to stay away from that dark corner in your mind which makes you think that everything is impossible and instead try to brush things off as minor issues.
