I went shopping with my mom and sisters. My mom paid for my sisters' items but she did not pay for mine.

How come? Is your sister a minor and are you an adult?
gpt
My sisters are all adults, I am the middle child.

That doesn't sound fair at all, I wonder why she did that.
gpt
I paid my bill and I felt so bad.

If I were you, I would ask your mom why she paid for your sisters; items and not yours. That's so mean.
gpt
It is very mean. I have a good job so maybe they think I am better off financially.

Now that I think of it, it most likely is the reason why; maybe she doesn't even think of it as a mean act and maybe means no harm by it. Regardless it is important to share how you're feeling with her.
