Fear, Anxiety and feeling unable to Cope are very common feelings for people with M E and often misinterpreted by the medical profession as the psychological cause of physical symptoms rather than symptoms of a physical condition. These symptoms are also often misunderstood by family and friends with many of those same family and friends thinking you just need to pull yourself together and get on with life. (Much easier said than done, even for somebody with a psychological condition, and possibly even harder for you with a physical condition combined with psychological effects).
Cause & Effect
It is not always apparent or easy to know which is cause and which is effect even for you so not surprising other people find it confusing. So how do you know when at the same time you are also experiencing brain fog / confusion, you need to remember what you are like normally, think about similar circumstances in your past and how you felt, so is this a situation a circumstance in which if you were well you would be feeling the same fear, anxiety and inability to cope, if not then it is a symptom, the effect of M E, rather than a cause.
Feeling unable to cope is a reality, you probably aren’t able to cope well, you are unable to think clearly, to focus, to even understand where you are and what you are doing, this is not an irrational psychological problem!
