235/365 Hair pulling stress

I had just spent most of this weekend preparing a presentation of my second year essay. This is like the main piece of work of the second year. I had not done the essay but thought I would work on the presentation because it was due in a few days and then I could use this to write the essay. So just as I was finishing late sunday night (today) I got an e mail from my tutor saying that he would not be in the day we have arranged to do our presentations and that we would do them in the first week of next term.
This is probably the worst time to do it since I have 4 eams that week, a group project and an assignment to do that week. Not only that but it's a week before the essay is due. He also said that we should hand in a draft of our presentation instead. Thanks for the short notice BRUCE. I have no draft to hand in and could have spent the weekend getting this done but instead I have wasted it making a presentation for him that I no longer have to do. Sure I should have done a draft by now but I have had a busy term and didn't. My tutor is always cancelling last minute, not replying to e mails and generally being useless. I may request to change.
