Mindlessness over mind

Since when did I become this person? Since when did it matter what someone wrote to some one else? Since when did I become insecure about things the weren't even my concern in the first place. Since when did something affect me this much!? Well I suppose I have been affected by things in general, pretty easily. Something/someone with even an ounce of persuasive powers could get me. Unless I was stubborn about it. That aside, I don't know whether I should be happy or go into panic mode. You know this constant state of paranoia you are in, even when you are actually doing something else? I think I might be getting there.
