Missing Storage Space after deleting volume

So recently I upgraded to High Sierra, but after a few minutes, I wanted to switch back to my Windows 10, I held Alt/Option when the startup sound came, and then I saw that the Windows disk disappeared, I panicked a bit, I went back to Macintosh HD, went to disk utility, then clicked the info button for the BOOTCAMP disk, I saw that bootable and about almost everything said: "No", I decided to try to erase the partition by clicking the Erase button, it was erased, then I converted it to a volume and then I deleted it. Worst mistake I've done, I noticed a big change in my storage space, about 500 GB was gone from my 1 TB SATA Disk, I tried using the fsck command (Sorry I'm not very experienced in the Terminal or Command Prompt.), to repair my computer, I booted back in to Macintosh HD, the problem was still there, and I can't make another partition either, it just says after a second : "Sorry, the operation failed.", and when I tried to Install Boot Camp Again, it said: "An error occurred while partitioning the disk. please run disk utility to check and fix the error." I had already reinstalled MacOS and that wouldn't work, does anybody have a fix to this? If there isn't, is there a way that I could wipe my mac and get everything repaired? I do not mind losing data.
