Anxious

It's strange at times because I'm afflicted with, perhaps, anxiety? I can't sit in my chair properly. I feel like I need to do something. But I'd rather do nothing than do something because doing something is hard to concentrate on. I feel like there is a beast upon my back and I must wrestle it off. Only when I can occupy myself with something extremely distracting can I forget about this beast. I cannot even play games or enjoy myself or whatever. All I want right now is to do many things at once and get it over with. This is not unusual, sometimes it takes a cleaning of a room (one hell of a cleaning) to purge myself of this feeling. Sometimes it takes drawing out a stream of thoughts onto a journal. Sometimes I just cannot sit still and do what I am assigned. Is this the affliction of a teenage boy? Is this the affliction of an anxiety-ridden man? Or is this the affliction that I have been born with that disables me from focusing on tasks and completing the said task? I do not know, but I do know that I have just blurted out a few sentences with great impetuosity that it has relieved the feeling somewhat.
