What have I ever written here that has made me look better? 
Honestly, how would I or anyone else know. Even those of us who want to be completely honest, inadvertently color what we write to make ourselves look better. I suppose there are some folks who have such low self esteem that they actually make themselves appear worse than they are. You don't strike me as such a person.
I'll give you that from what you posted over time, you seem pretty honest. Well, except when you posted that you'd died in a car crash. You posted about your issues with alcohol and that takes courage. Most folks don't want to admit that they have a problem with alcohol.
Sometimes your posts are particularly mean and sarcastic. Is this the real you? I doubt it. Everyone has their moments, some are good and others not so good.
