Getting burned

My heart is hurting right now.  On Saturday night, at a derby bout, one of my close friends, F, said something that I'm having a hard time getting over.  She and her fiancee were sitting higher up in the arena, but I wanted her to sit lower where there was room for our other friends as well (there were 7 of us and they had only saved 2 seats).  After lots of arm-waving and head-shaking, I went over to talk to her.  She told me that she liked her seat better and said harshly, "It isn't the end of the world if we don't sit together."

Maybe that doesn't seem to be such a big deal, but let me explain the background.  A few weeks ago, F was having major problems coping with all the events in her life.  I spent an evening being there for her and even drove her home in her own car because she was unable to drive herself.  She was so manic that she committed herself to the psych unit the next day.  I took time out of my Friday evening to visit her in the hospital.  Then when she said she needed fewer visitors so she could get better, I gave her space.  However, I still spent a lot of emotional energy worrying about her. 

She came home over a week ago and Saturday was the first time I'd seen her since she'd been released.  I really wanted to sit by her because I missed her and we hadn't had a chance to just hang since all the chaotic stuff happened.  In addition, my week had been crazy intense, and I wanted to be near my friends.  I needed her support that night.  Also, F is actually on the derby team but wasn't bouting due to the hospitalization, so the only reason I was even at the derby thing was to support her and our other friend on the team.  Derby's ok and all, but if I didn't know people I probably wouldn't be at the bouts.  I'm not that into sporting events. 

I felt really rejected by her comment.  She has apologized, but I'm not sure she totally gets it.  First she said she was sorry for snapping.  But it's what she said, not how she said it.  I have been nothing but supportive and this is how she treats me.  Then she made all these excuses, like she was moving, wedding planning, her fiance just got back from 3 months in Japan, blah blah blah.  I totally understand that she is going through a rough time.  I really do.  And I have excused a lot of her behavior.  HOWEVER, I don't think that gives her license to treat her friends like crap, especially ones that went out of their way to be supportive.  It took a lot of my emotional energy to take care of her.

I will forgive her, and we will still be friends probably.  But I think I am going to have a hard time getting close to her in the future.  The next time she goes through a tough period, I might be a little distant.  I don't want to hold a grudge, but I'm also afraid of putting myself out there for her and getting burned.
