wireless in uni (yeah) & more depression (no yeah)

yeah~~i can now actually use my laptop to online with my uni's wireless service (as i'm doing now). That makes lots of things easier for me, for one thing, i can use msn. lolz. Anyways, things are getting more and more hectic and stressful for me. Exams are just around the corner (next week), after that, week 2 will be my trial OSCE, and after that, the following week (week 3) i'll be starting my clinicals. That'll last for two whole months, and in those 2 months, on top of all the revising, i'll also be having clinical assessments and assignments (was totally stressed-out when my lecturer brief us on our assessments). After my clinicals, i'll only be having a short study week before my end of semester exams with the real OSCE (and it's not spaced out). I'm as good as dead after all these. My head keeps throbbing and throbbing....sometimes, i feel like screaming and sometimes i feel like crying.....seriously, i'm on the brink of going insane...nuts, mad, cracked, and soon, i'll be over the edge..falling and falling and falling till i "pulp" hit the bottom then i'm no more....see.....i am already not in my right mind.....>.< yup, now i'm depressed again, just don't understand why my mood swings can be so extreme.....*sigh*....
