Stupid Me

I've always been stupid when I do something,
Or after I've done that only I realize I'm such an idiot,
And then I'll be so unhappy with myself,
Like now,
I don't like that,
Even thought I were being stupid,
I wanted to get it over it,
But it's like a thorn in my head,
I hate that,
Can't find the heart to do anything,
I'm uninspired,
Hmm...

What do I do to cure myself?
To find back my "heart"?

Sad case.
