She is always leaving me out. What do I do to make her notice me a bit more?
Hey there, thanks for writing in. Looks like you're losing connection with your friend, and you'd like to get back into her picture.
I think if you try to "make her notice [you] a bit more" then you're going to get into trouble playing mind games with her, rather than getting your needs met directly.
You need and deserve attention from a friend. I wonder what it would be like to talk to her about it. Do you think she realises that you feel left out? Sometimes people can be so caught up in their own world, they're not aware of how their friends feel. If she values your friendship, she'll listen to you and find out a way that you can still feel close. Maybe she can take turns sitting with you, or you can compromise by sometimes sitting with the "popular girls" who you don't like so much. All of these things can be sorted out by having a couple of easy chats.
At the moment, it's really hard for your friend to read your mind and know how you feel. On the other hand, if you don't think it's worth it to have an honest talk with your friend, it might be more useful for you to build stronger connections with friends who suit you better. Maybe there are other friends you have who would notice if they left you out of the circle?
Hope this helps
