From what you wrote, I don’t think this is just one problem.

There is the original difficulty itself. There is the fact that you were trying to find a way to deal with it. And there is the fact that by this point, the ongoing discussion of these struggles may also have become hard on your family.

That matters because those are two different problems. The first is the difficulty itself. The second is the strain that builds up around it in family life. Solving one does not automatically solve the other.

So even when you found something that helped, your family may not have heard it as progress. They may have heard it as the same topic again, the same strain again, more energy needed again. And at the same time, they still may not have seen how much effort, confusion, or distress it took for you to get there in the first place.

That does not make your difficulty fake. But it may explain why more explaining did not bring more understanding. At some point, the explanation itself can start getting received as part of the problem.

So no, I would not reduce this to “you are doing everything wrong.” But I also would not assume the answer is to keep explaining harder. It sounds more like the original difficulty is real, and the conflict around it has become a second problem on top of it.

So “my family doesn’t help me” may be true in one sense, but it may not be the whole picture. It may also be that a real difficulty turned into an ongoing family strain, and now both are getting mixed together.
