I'm glad you're asking for similar experiences specifically, because otherwise I'd feel guilty about only talking about myself and not being able to help you.

I don't view what others call "my needs" or "my limits" (they basically come down to the same) as "needed" or "a limit".
For example I have a disorder in my hand and someone told me to mow the lawn. I did so, and it hurt. When that person commented on how well I'd done it, I said it really hurt. He said "So you can't mow the lawn again." Of course I can mow the lawn! It just hurts.
If I need ten bucks for food and my friend is spending his last ten bucks on weed or on cinema tickets to take his girlfriend, what right do I have to ask him to loan me his money and limit himselves?
Why would people want to help me? Even more, what right do I have to ask for help or even say "I need this" when I can clearly survive without it (even if it makes me unhappy) or "I can't do this" when I clearly can, it just hurts a lot?

I have this problem too at school when classmates go home because they have a headache or something. I always stay at school unless I'm bothering my classmates with being ill (fainting or something is rather distracting), vomiting, or have a fever. Yeah, my head hurts, and being at school makes it worse, but I can be at school so what right do I have to go home? Or say "I can't" when I can? What right do I have to say "I need" because there is no reason for the other to care that I 'need' (I prefer 'desire' or 'could use' because most of the time you don't really need so-called needs). I have no right to ask him to do something to me, give me his time or attention, thus there is no reason for him to do so, so I don't.
