You could be my son talking. All the things you are experiencing, he experienced. He too talked about the headaches, the sore muscles, the stuttering, the loss of words, the irritability. He did not reach out for help, did not access his health plan, did not disclose how he was feeling, He left it too late and he 'broke down' totally in December. Now he is literally at the bottom and searching for a way up. Please my dear, reach out now and let people know how you are feeling before you have reached saturation level.
