STOP sign means you must stop posting crappy content, @ablckbrd.

SHORT ANSWER: You cannot delete your post.

Although you can edit them. The thing is, I do not know if this is against @steemit's rules, but I happened to post something really worthless and downright negative and I absolutely regretted it, so I thought why not change the content?

I actually posted something like a call for help because I was a a bit suicidal yesterday. But today, I changed it into a Sunday Currently post. The first post's title has something to do with me wanting to die but I am also a scaredy-cat. With "Fuck life!" as the content. Classy, right? So I changed it today. I even got a reply from @philippinetrail that says, "Hey cheer up!" of which I sincerely appreciated with all of my heart!

Sunday Currently Vol. III

Lesson?

Do not post something you'll regret later. And cheers to exceptional content, Steemians!

FYI:

I do not encourage people to do this, because this might lead to unhealthy practices.

P.S. Please enlighten me if this is valid to do. Although I am pretty sure I am not doing it again. Cc: @steemit @steemph

Namaste!
