Macbook Air Mid-2013 loses storage space when files deleted

Specs : Macbook Air Mid 2013

Processer : 1.4 GHZ Intel i5

SSD : 128 GB

OSX 10.10.3

RAM : 4GB

So one day, I turned on my Mac and saw that it had 0MB of storage space. So I started to delete some of my stuff (7GB) and then it went well until I restarted my Mac. After the restart, the storage capacity went down to 1.68 GB. What I don't get is that my files are gone but what happened to my disk space?! Used Bitdefender Virus Scanner to scan (thought I had a virus) didn't work. Also used disk utility to try to repair disk, said disk was OK. What should I do? Is there something I have done wrong?

MacBook Air, OS X Yosemite (10.10.3), Mid 2013
