How do you delete an account?

I need to get away from this site, it's cost me everything I have, the woman I wanted to spend the rest of my life with doesn't trust me, I've lost my house, my family...everything! How do I delete my account? Oh and for the record, this is my only account so to those of you that said you knew me on multiple accounts, thank you for helping ruin my life with your lies...Sure I've made mistakes in the past but this was my only account, I changed my name a few times but never had a different account...my life stinks and I guess I have nobody to blame but myself...farewell to all, good luck with life I hope your life turns out better than my miserable existance did....good bye
