Yes, I have a sort of barrier between myself and the world these days because of the cognitive issues and brain fog.
All of my emotions, thoughts and many experiences are dull/flat because of the permanent brain fog.
I don't think we should underestimate the consequences of having permanent cognitive impairment.
But, because we spend so much time isolated and without normal physical, emotional and social stimulation, it's quite likely that many of us might experience some form of mild or major depression during the course of our illness. Depression can last for years on end, and it can take the form of a very slow and gradual onset. Mild depression can be impossible to detect especially if it comes on gradually, because it can just feel like our character is one that is naturally low in positive emotions and feelings. So it can be easy to mistake mild depression for personality or character.
With depression, you can lose your emotions, feelings, enjoyment, motivation and sense of self. Also your senses can seem dull. The meaning, motivation and purpose can disappear from life. For many people it can feel like there is an invisible barrier between themselves and the world.
There's a type of depression that you can get where you don't feel strong negative emotions, but you just lose the positive feelings/emotions from your life. So it's not so much a negative experience, but it's a lack of positivity. This type of depression is very distressing if it lasts for a long time, as it starts to colour our whole life experience. Life slowly loses it's meaning, as much of the complex richness of life is lost to a dull fog.
Redo, Mark and JoC, from what you have described above, it is difficult to determine if you have described a cognitive symptom of ME, or a form of depression, or possibly both.
But the lack of positive emotions described above, suggests to me that there could possibly be a touch of depression going on for you.
ME can dull the brain a lot, but it doesn't necessarily wipe out all positive emotions, although I think it can do.
So if you haven't tried anti-depressants, then I think your description of your feelings would qualify you for being prescribed some, and I think it might be worth trying them out just to see if they make a difference for you.
If you try antidepressants and they don't make a difference, then maybe you don't have depression, but at least you've given them a try and ruled out the possibility of depression. But please note - everyone responds differently to antidepressants - if they don't work for you at first then it is worth trying a different dose or a completely different type of antidepressant.
Not everyone likes anti-depressants but many people find them very helpful, and often a life-line. So please don't believe the negative hype surrounding them. I think that people have to decide for themselves whether they are helpful or not.
In my experience, absolutely no herbal remedies (except some types of St John's Wort), or vitamins, or other types of supplements work like anti-depressants, although some supplements may have a very mild effect on mood for people without depression.
And I wouldn't recommend St Johns Wort, because it is not reliable, not all brands are effective, you have to take a specific amount of the active ingredient, and it has dangerous side effects and drug interactions.
Anti-depressants are a lot safer and more reliable.
Also be sure to get your thyroid levels checked, because a low thyroid causes low mood.
Personally, I would not suggest Wellbutrin as an anti-depressant of first choice. It is very stimulating, and works primarily on noradrenaline, which is a neurotransmitter which acts more on stimulation than on mood (although this might suit some people). This artificial brain stimulation might not be suitable for people with ME because we are so sensitive to exertion and stress. I think Wellbutrin also might have more side effects than some others. If you think you need a stimulating antidepressant then one of the SSRI's might be helpful. If you need help sleeping, resting or calming down, then one of the tricyclics might be helpful.
I don't know if I've answered any of your questions... I'm just exploring the subject...
I've had many years personal experience of depression, in the past, and so i've got quite a lot of insight into it.
Please ask me any questions, if I can help further.
Take care,
Bob
