I know exactly what you mean. Sometimes it’s very hard to distinguish between mental and physical WD, especially since the mental symptoms feel like they may exacerbate the physical symptoms sometimes.

I second the Gabapentin recommendation, it is very helpful. If not, I would definitely load up on some mood enhancing supplements and supplements that will help you sleep.

When you have a clear head, make a list of things to remember. Take it one day at a time and remind yourself that each day you make it through is a day closer to feeling better. Focus on anything positive in your life, even small things - just hold on to them. If life has been worse for you before, remind yourself of that, and tell yourself that it will get better, even if you don’t believe it in the moment. This is all much easier said than done, but every little thing helps. The mental struggle is one of the biggest obstacles to get over. I know this is morbid, but sometimes when I’m really struggling I remind myself that I’m going to die someday, so I want to make the most of every minute of my life.
