Oh wow...get outta my head! I even do with this with people I'm close to..."!$% I said too damn much!" and then disappear for weeks convalescing from the attack of verbarrhea.
I do have an online journal and I spend a great deal of time writing in. I get embarrassed about stuff I wrote there and have had to tell myself to just leave it. Try to find meaning/make sense of why I wrote what I did.
