Startup disk almost full message

I am getting a startup disk almost full message on my Mac. When I check the storage, it shows almost every single GB being used in the system section. I have deleted all of my pictures and everything extra and it freed up about 1 GB, but then the space went back down to only 8 MB available. This started happening a couple days ago, not long after the new system update. I have tried the clean my Mac, but it did not help. I have also tried starting my computer in safe mode, but it shows the same information. My battery has started dying a lot quicker now than it did before and is running very slowly. What can I do to fix this? I have only had this computer for about 6 months.

MacBook Air, macOS High Sierra (10.13.3)

Not much, I'm afraid. I suggest you backup your files while you can. The end is near as this alert is a precursor to total drive failure. The only cure will be to erase the drive and start from scratch. You need to free up at least 20GBs.

How to Free Up Space on The Hard Drive

You can remove data from your Home folder except for the /Home/Library/ folder.
Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
Also, see Freeing space on your Mac OS X startup disk.
Free up storage space on your Mac.
See Where did my Disk Space go?.
Be sure to Empty the Trash to recover the space.
Replace the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Use OmniDiskSweeper or GrandPerspective to search your drive for large files and where they are located.
