No, you aren't "yourself" in any sense that you could meaningfully account for. Whatever substrate lies below yourself is not accountable to you, and in all likelihood neither to itself or to anything else. Yet it is this unconscious substrate that is somehow responsible for most of what you do, without being accountable for what it does--only you may take the blame. There is little sense beating yourself up for biological processes in no sense under your control, though there may be a biological process beyond your control that, for no reason, predisposes you to assume you ought to be held responsible and to blame yourself when you lose control.
