(((((hugs)))) IMO you're overthinking.

I can do it too, btw, but I have a T to stop me.
When we expect others to understand, when we want and expect them to help us, and they don't we turn the anger at them inwards on ourselves...usually.
Try and forget about them for a bit? Focus on yourself, and what you need and what of that you can do for yourself. Make some difficult decisions -without them bothering you - for good self care.
IF you could have what you need, what would it be and can you arrange it for yourself? Relying upon others who just don't get it is very frustrating!!! YOU get it. YOU understand... now go after it. Find professionals and add them to your support team. Sounds to me like you don't yet have any support team.
I think 3-5 people who you can rely upon for support would be a good number. And each one doesn't have to be totatlly supportive, but at least in one area of help that you need... if the people around you won't understand and help, then find some who will.
