It happens, and is normal, especially after the holidays, and even after treatment when we are at our high points, and in fight mode, only to be let down wondering what do I do now? Some post to help others to help themselves or go to group H&N cancer meetings. Life is a roller coaster ride with ups and downs. I'm pretty positive also, but I don't go around with a permanent smile painted on my face, and like to keep it real, and so are my emotions. I hate rah rah, blah talk, and just need an ear to listen to sometimes, but the problem is, most people don't listen. If these downs become constant, interferes with your daily living or have life ending thouhts, maybe you need to speak with a professional, and some even needs meds or even to reduce them. Some meds for neuropathy I took are antidepressants, anti seizure meds, and felt better mentally without, so I stopped taking them. I guess they can effect everyone differently. A little exercise, fresh air does wonders for some. You may want to have blood work done also to see if you suffer from any deficiencies, some which can cause depression, that can be corrected.
