It should not be that hard.

I feel ok but am shacking pretty bad. I get this way sometimes not sure why. Its like being on the edge of something about to happen without a reason why. it does not make any sense to me. Loud or sudden sounds push me closer to that edge. Some times I think I see movement out of the corner of my eye but there will be nothing there and my eyes hurt even at low light levels. RA pain increases but I think it is as a result not as a cause.If this is a chemical imbalance in my brain why would it change so rapidly? Have not used illegal drugs in over 25 years but could this be from using LSD in the past? Is it from a build up of legal drugs? It has taken considerable concentration to wright this and be accurate. It should not be that hard.
