Did you ever give up on a game because it was too hard?

I'm rly ashamed to say it but I never beated the final boss of Paper Mario: the thousand year door. That boss was so hard for me that I decided to take a break from it. I think I also received a new game that toke all of my attention. When I decided to go back into the game, I forgot how to play so now It would be impossible for me to beat it unless I start all over again in order to relearn all the strats and the mechanics.

Also I remember what totaly discouraged me, the boss had 2phases, and once phase 2 starts we receive all our hp back. But I did'nt know that! So phase 1 was already tough and I was near death, I used a golden mushroom (to receive all health), one turn later I entered phase 2 and received again all my hp back. So I totaly wasted my golden mushroom and I died in phase 2, that's what totaly pissed me off and I decided to take a break.
