When stuff begins getting emotional from stress try looking at your issues with complete objectivity, that way you can see the pathways to overcoming such obstacles clearly. You need to make things simple, in the HSC I am finding I start becoming too unproductive and having negative outlooks when I start to think about everything as a whole, for example "how the hell will I do adequate study for all of my subjects in 3 weeks till trials". To not begin thinking about how I should escape the HSC by going to some forest and surviving the rest of my life there I decided I will just focus on small things like ok, 4 topics of physics lets do that 1 topic a day and past papers once completed and bam I should be set decently for physics (after move onto chemistry and so on). You will get through this, it isn't the end of the world by any means, just do the best you can from now on because quite frankly that is the best course of action for any situation. *hug*Forgive me if this isn't the right place to put this, I'm new here.
Anyway, my major work for one of my subjects is bugging me and my progress (or lack thereof) has placed my last in my class. It shouldn't be worrying me as much as it is, but it's causing me some grief and I could really use a virtual hug right now...
