If you wouldn’t constantly restart your node(s) then emptying trash would finish for each of the directories.
Stop tinkering with your nodes. Let them run and all the processes will finish eventually. I might also help not to run a node on a potato 
The amount of folders in the trash folder is not normal. My guess is that they’re all partly emptied because you restarted the node again and again before the emptying could finish. Check the amount of empty xx folders with
find /path/to/trash -type d -empty | wc -l
Maybe some of these date folders only contain empty xx folders. To delete them run
find /path/to/trash -type d -empty -delete
If your OCD wants the oldest folders gone, delete them manually.
