Same goes with what you said, losing is part of gambling, accepting it would be more easy to move forward than keep on regretting,
We have our own treats with our losses. And for sure different in terms of amount that we've used for our initial bankroll,

The last part you have mentioned is very much true like if we have lost we should not be too much depressed or keep thinking about it continuously because they both are two sides of one coin and win or lose both are normal as one brings joy and other sadness but it's okay and we should move on to the next game with one more hope.
Never chase losses that is the golden rules

Just gamble with enough budget , not over and not less so in chance that you lose now then go home and rest for a while.
try to come back in the other days because there might be a luck that will come your way.
we have been on this same scenario , and we knew what will happen, lose now or lose forever .
