I lost my appetite and have trouble sleeping, does that sound like withdrawal from Norco?

I have for a year been taking Norco 10/325. 3 pills a day and 2 of them I take half at a time. I had a serious injury years ago with my left foot. Accident broke 3 bones, fractured 2, shattered 1 and dislocated it. Than over the last year have had many surgeries on my jaws. So I have a legitimit reason for taking them with chronic pain now. My Dr keeps a close watch on my body and last test showed no dangers in my liver. A few months ago I found myself taking 5 a day. Caught myself and dropped back to 3 max a day. The last 3 weeks I have been waking up feeling so scared and depressed and even fear and anxiety. And of course the bathroom part which starts only 12 hours after the half I take before sleep. However, things that never bothered me before all come to light in the mornings. Things like world problems. The election, North Korea, terrorism and so on. These things never bothered me up until a few weeks ago. Now I find myself scared of even dying with the world problems. I realized today that its because of the Norco. I dont take much though. I take a half in the morning a couple hours after I wake up and I feel better and realize the things I was worrying about I dont worry as much about after I take it. I was at the same time trying to get off Paxil and I thought that was the problem and ended up going back on the Paxil which did not help me at all. Thats when I realized this morning it has to be from the Norco. I go right back to taking it as prescribed because it helps me think better and clearly and get through the days. I also lost my appetite and sleep very badly. I HATE the feeling but I know now what has happened. Seems when I started backing off the 5 a day is when I started feeling this way. I will not take any more than 3 though a day. I can limit myself to what it says to take. Half a pill each dose helps get through the day. But than again I start feeling the pain. I want to test my theory just once to see if I am correct. I will wake up early in the morning and take a half and see how I feel when I wake up. When today I realized why I am feeling so bad, I felt a little better knowing that the problem is not with me. Its the medication. Does this to anyone sound like withdrawal from Norco? From what I have read, this is exactly what I am feeling. Thank you.
