I am sorry you feel like you have to leave this site. I doesn't appear we watch any of the same drama types, so I likely haven't read any of your numerous reviews, or used any of your lists, but they seem to be a nice contribution to the community from what I see by browsing your profile. It would be a shame to lose that many reviews and lists.
If you are serious, you probably could use the Support section of this forum and ask a moderator to delete your profile. Maybe just not log in for a month or two and see how you feel about things? If you want to come back you could even start a new profile and just leave the old one for archival purposes.
