Confusing....

Erh...how to say this, is it common for old memories or feeling to suddenly flow out?
Is it really simple to get caught up in faint memories you'll want to conceal forever?
...Suddenly things I thought I forget flow out like a ravine of chaos, just because of that accident~~
Its like an urge driving one towards the despairing cliff...That one accident just made me crumble again, i mean..its like making me mad, getting me obsessed all over again after so long...GOD SAVE ME!!! T-T
