There are some shots and some situations you simply cant do very much about so, dont worry, the important thing is that you learn what you can and then forget about it, move on and dont give up.
Its happened to all of us, some of more recently than others
but, i guarentee you will bounce back from this. The last time i let in double figures, i won 3 of the next 4 and got MVP in 2 of those games.
