hi MM i really do feel for you
you really could be writing about me
it may help you but this is what i would do
leave the housework and garden its not priority at the moment
prepare for your presentation because that is the most important at this time
quick run round to do the shopping you have to eat to keep your strength up
when are your exams maybe you could write yourself a time table, remember it wont work if you try and cram everything in
revise for 20 mins have a little break then go back to it for 20 mins
good luck MM
