I am having a difficult time concentrating and getting daily tasks done. As much as I need to work and go to school and live a so called "normal" life, I just can't seem to put out any energy or focus on these things. I am mentally and physically drained. I am so overwhelmed with everything in my life, causing me not to feel the way I should. I cannot eat or sleep right, I get these crazy mood swings, I cannot concentrate on anything, and sometime I have noticed my memory isn't that great anymore because I am forgetting things easy, I have constant headaches and pains in my back and shoulders. I do not feel right and I am scared because I can't seem to motivate myself to do anything. This is not me and I do not know what is wrong with me. I have felt this way off and on for the past year and a half, but has got substantially worse in the past couple of months.
