Ok, I did something real dumb. I went to my inbox and marked a few messages that I wanted to delete. Instead of clicking on "delete marked" I clicked, "delete all." Now my Inbox is empty, and I needed to keep some of those messages. Is there anyway to get them back?
you can try asking a mod to restore your most recent backed up PM's, all of them won't be there but it's better than nothing
I don't think you could get it back. But like d11m said, you could try contacting a mod and see if they could help you.
