Not really.
Im not depressed or anything, but almost a year ago now, I let someone special go I really shouldn't have due to a very childish action of mine. And regretted it ever since.
Unfortunately us splitting up probably happened for a deeper reason in hindsight, but my actions have really f**ked me up, and would go to say im still pretty f**ked up in terms of hating myself over it, still.
Seams sadistic, but going out and punishing my body by pushing my fitness further and further seams the best way to get my mind off shit.
