When I went through my old emails, I only deleted the emails from former POAs and boyfriends from my Inbox folder.
I forgot about the Sent folder.
So I got to re-read the breakup emails between me and J. (a man I dated briefly while L. and I were separated.) Luckily, I didn't get crazy and miserable from this — just a little sad and “blah” and wishful. I turned to my HP about it, did my daily gratitude list, and read on this website and on some spiritual websites.
But I could have saved myself a day of discontent and whining if I had deleted all emails from J. from ALL folders - not just the Inbox folder.
