Have I lost my mind?

Right now I have this strange feeling of anxiety. It's like I'm sitting in the electric chair waiting for them to throw the switch. I can't pinpoint what or why or how but something is bugging the **** out of me. The only other time I've even felt close to this was over 13 years ago. It's almost a state of panic. It's a total feeling of being helpless. A total complete removal of all hope. I imagine this is how a martyr feels right before he or she takes their own life for what the feel is right. It's been a long time since I've felt this way. I've always been able in the past to know what was bugging me. I've been able to take myself apart and see what the problem was. Never have I been completely blinded like this. It's almost as though all my fears have rolled up into one. It's so hard to figure out the problem because anything that does bug me can be clified under this new feeling. There is bad acid reflux and clumps of hair. Uncontrollable shaking, problems with thought control. I'm unable to focus. I've always been in control of my emotions. I've been able to make myself be happy or sad. Always been able to calm down from anything by just taking a step back and talking to myself. I can't accomplish that this time. It's like I've lost control. I can only wonder if I have come to the end of my rope. Have I lost my mind?
