Black answer to side invasion?

I played this game as black:

I was obviously way over my head as anyone can see. :slight_smile:

I was reviewing the game and found out I have no idea how to answer to white’s move 145, without getting a catastrophic invasion for white. Obviously my move 146 was not right, but I can’t find any move that lets me save my skin here.
So maybe my move 144 was the mistake? Surely there’s some possibility of making two eyes in my corner group?

Any thoughts will be appreciated!

I left a few variations in the game. In this particular case, I think you answered correctly, but move 148 was a big mistake. I also left some other answers that are normally played in this kind of situation.
