Quiting Bootcamp Problem

Heres what happend.

I tried to get windows on my mac with bootcamp. While it was downloading the partition, my applications started to freeze.

So i decided to quit bootcamp with Command + Q , but after that, i check the terminal , and found out i lost 150 GB of memory.

I checked the Disk Utility and I only found my Mac disk, and no other partitions.

how to i get back my 150 GB?

heres a screenshot of Disk Utility and my Mac information:
