Clutter, cluttering, cluttered

Have no idea why, but the resolve to quit became strong (again) tonight, after the meeting.
Is it the environment? The people? The Principal? The shift to the new school?
Or simply because I simply had enough?
I have no idea.
Feel that I have taught nothing over the year... over the years in fact... Are the kids really benefiting? Do I have too high expectations of myself.. or am i really a lousy teacher? Feel so incapable, so unaccomplished and even angry with myself sometimes... feel very often that i'm doing a really lousy job...
And what are the shit stuff i have to do? Of course every job is the same... and perhaps this is one of the most enjoyable job I'll ever land myself in...
But so what...
If I'm sick of it... I should move on ya... after all, I'm dealing with lives... I may be detrimental to the children's development...
And of course money is also an issue... the main issue in fact...
I'd love to trash all my worksheets... all my resources... throw out all the stuff that's giving me a headache... Can't stand the clutter in my class... can't stand having to pack and shift... Wanna break free and detox... physical clutter... mental clutter...
Break free from lesson plans... from printing and cutting resources that don't get organised... Just wanna throw throw throw...

And I see this as a sign-
today, for the first time in my life, i did half my lesson plan for next week... on a WEDNESDAY!
And guess what happened.
Some virus in the school computer wiped out that file... gone...
What's the point...
Working so hard to motivate myself... to convince myself i should stay and press on...
To be positive about doing lesson plans...
Look what happened...

Sigh.
Am I being impulsive... or should i really just leave...
