But how does this explain the fact that, I can try so hard to get people to like me- helping out and being there when necessary- yet people still don't want you around? I'm still not part of the group.
You answered your own question: because you're trying too hard. It's a shitty reality, but the more you see of someone or something, people tend to take it or the person for granted.
Look at the market and law of supply and demand, for example. If the marketplace is flooded with the same kind of product, the demand for it is low and the prices are low. The product isn't perceived as valuable because there's so much of it out there desperately vying for people's attention. Sometimes its even
annoying when its constantly advertised, because people know if they
wanted it, they could go out and get for a dime a dozen anyway. People hate being reminded of what they already know.
But if you introduce a product where supply is low, demand goes up and the value goes up. And the catch is, sometimes its even the same product that was everywhere before!
And yes, I just compared social dynamics to capitalism. But isn't capitalism fueled by the fickle nature of its buyers (people)? It's an unfortuante parallel, but its true.
You're only disrespecting yourself if you keep trying to please other people. And if you don't like yourself enough to have a sense of your own respect, you can't expect people to treat you differently.
Being a doormat doesn't make you a good person, nor do you
have to be a doormat to help people. Have your own say, and don't change your values or compromise your time just to fit another person into your schedule because you want them to
like you.
Try this experiment: say no every once in a while.
