Does this seem a little weird?

I'm with my friend a lot bc she takes me to school & stuff. We've been friends since freshmen year, always have been really cool. She's given bday shout outs to all of her friends (ones she barely speaks too) on her Instagram but never me!! She also always takes pics of her with friends and posts them, not one with me though... Even one time she was like "hey can you take a pic?" I thought she meant of us together but she wanted me to take it of her and her other friend.. Wtf?
