It doesn't matter what your level of experience is, losing hurts especially if there was a big stake and you were wholesomely confident in it. For me neither I don’t forget a loss so fast and most of the times it lingers for a day or two in my mind. But as you said a win right after does clear that right away. What really gets me moving on is analyse itself, not just emotionally, but also logically though. Was it poor decision making or just pure bad luck? When I sort everything out I feel somewhat at peace and ready for the next one.
We hurt ourselve the second time whenever those losses dont get acknowledged or accepted. When we say things like, I must get the money back, the house can't get away with it this time, the pain and agony of the lost money begin to linger for a longer duration. Which riskst the happiness of the player due to the fact that all the effort invested in recovering the money isn't working. The best thing to do is accept the responsibility and play better on the next session. Also your last lines are valid too.
