So I have this friend. every time I'm around her other friends she seem less engaged with me?

Or when she goes out she never extends the invite to me. But always seem to bring up the fact that she went out with others. I don't mind but I can't shake the feeling like when other friends are around it like "why am I here". And I don't want to be anywhere I'm not wanted. What should I do or am I being over dramatic.
