Is OTHER wrong in the post ? POST : Hello everyone,

Yesterday I was supposed to see a friend at 2pm. I was ready to leave my house when she texted me she couldn't make it today. However this is not the first time she has done this to me, actually it is the second time this week. It's been almost 3 weeks since we try to see each other but everytime she either have something else planned last minute or didn't wake up.
I feel really bad about all this and I was kind of angry at her when she told me she wouldn't be there yesterday again. I think I may have hurted her (I'm a really calm person usually so it may have shocked her). I also wasn't mean in my texts.

So, AITA for being upset at my friend ?
