unexpected visit from a friend

My friend Mecca called today, said she was in town and did i want to do anything? Mecca's always like that, rather unpredictable -- but when she calls, i jump at the chance to see her because if i don't it might be a year or more before i get another chance.  we've been friends since kindergarden, and it's a little strange to still see her.  

We have so much history together; distance has not divided our friendship, and she still has the quirky, wild manner of someone who really doesn't care what anyone thinks.  but she also has a very negative way at looking at people... and if she thinks she'll fail at something she won't try and then she'll blame everyone around her for being stupid.  although, she deals with so much, it's a marvel she's functional at all.  i love to see her, but we're growing into such different people.  how do you tell someone so independent that you're worried for them?  how can you say that you want to be there for someone you only see once a year?
