My lack of ability to psychologically condense events

[Rolen]

Example. I have a poker bankroll of 5K. I double it in a day playing limits I shouldn't. I drop half of my profit during the next day leaving me with 7.5K. Here is the eventual outcome of my hypothetical two days as I see it now, without having recently experienced it ..

A) I have won a large (for me) amount of money in two days
B) I have been lucky enough to win at limits with huge variance considering my bankroll
C) I now have a bigger bankroll than I previously had.

Now, here is the outcome as I see it of my hypothetical two days if I have just experienced it ..

A) I JUST LOST 2.5K. THIS IS A LOT OF MONEY TO ME. [censored].
B) ..

I find it impossible to 'look at the long term' in these situations, and see that this was in fact a positive outcome. Is there any way I could go about training myself to do so?
