I"m doing the same degree and I have had to plan out already how I am going to fit in the pracaround the house, a husband and four kids LOL. I am only doing a part time load of two subjects a year till my youngest is at school so maybe you could drop a subject or two and do one subject and your prac for this semester and maybe the load will lighten for you to feel like you are staying on top of it all. Plus you could always ask for an extension on your essays - they might say no, but it's worth a shot at least.

I hope it all works out for you.
