This article picks apart a bunch of biases by the researchers of a given paper. The object of study was the differences in behavior between a group of autistic people and a group of non-autistic people when choosing between prioritizing value for oneself or value for the community.
I recommend reading the paper itself too. If that is, understandably, too much for you, I suggest you go for the introduction, the conclusion, and the segments mentioned in the article.
You need to take care of yourself first. Don’t set yourself on fire trying to help other people. It’s ok to say no if people are always asking you for stuff.
