forgiveness : admitting the mistake we made or pretending we are always right ?

assalamualaikum...
and hello to all readers out there...
how should i start this??? i have lots of ideas but i don't know how to voice it out... im facing a phase which  i thought it is quite difficult to decide or find a solution for "that" things... i dont know how, and where can i find the best...best what??? omg, i lost my idea... im stress, under pressure and clueless of what is going on...
ok refer to word fogiveness, what did u really understand of it??? i still seek for it... i miss my mom and dad... and my family... it been long time we didnt hang out together, having dinner or lunch together... it just like flew away after one by one had their own fam... i miss the bench that abah make his ownself, where all of us spend our evening there... it such a beautiful childhood moment... even 8 of us had a cat fight most of the time...hahahhahah... and now, when one of my sis who i never speak to almost 6 years text me and seek for forgiveness from us, suddenly the tears dropped... and i knew, i miss my family... and she remind me, its not about the egoism of all of us, but it is all about our mom and dad happiness... i put away my egoism, my cold heart, and everything that make me hate some of them, just to say sorry and wish to stop all the nonsense conflict between us, coz im still remember, when mom called me and she is crying like a baby... it is not a tears of sadness, but it is tears of happiness... mom, dad, will you forgive us for what we did... 8 of us???
