Stressed!

I have had enough of people taking advantage of me and other people, of just assuming that people will do things without actually asking them first. Then who ends up being called up and asked what's going on? Me! Grr... I'm not the co-ordinator... I'm another mug being used.
Sorry, rant over... But I'm not going to sit back and let it happen again... either this stops or I'm out of this situation.
