What an interesting, and distressing discussion. Let me see if I can put some of my thoughts into words about what I have read here.
Aerose - so sorry to hear of the horrendous time you are having. I have t disrespectfully disagree with Calathea about the mental illness aspect. I do believe that derealisation, DP and many of the other symptoms mentioned by Aerose and others CAN be symptoms of M.E.
I have never resonated with the term 'brain fog' and never used it to describe my symptoms. What I feel is closer to dementia and derealisation. I luckily haven't had too much DP, but some.
I have feelings of living in a dream - everything around me seems a bit off and strange, light sensitivity is also part of this, with PEM I get severe feelings like I have just come in from a sunny outside into a dark room - ican only describe it as shadows and a grey veil.
I do feel attached to my family and children, but not so much to myself. I find it hard to imagine who I really am a ttimes and trying to connect the me of now with the younger 'normal' me seems impossible. I watch people around me living 'normal' lives, doing things like working and going out alone etc and I actually cant seem to work out how this can be done and how I could ever do this. I KNOW I used to do this, but cant seem to join up the old me with the new me.
I have experienced very severe anxiety and as a result of all of this have developed a weird kind of reactive agoraphobia. even so I reject the notion that I am suffering from mental illness. Even my regular GP can up with the oxymoron of reactive agoraphobia, as nothing else fits my case.
My functioning is not so bad these days - still mainly housebound and using a wheelchair for longer trips out and mainly to avoid PEM. I find the brain symptoms pretty bad. I am not intellectually affected - I am able to study, although it causes severe PEM, but I feel often as though my brain is inflamed.
strangely I can actually 'feel' my brain, or so it seems. I also keep experiencing brain sensations where my brain feels as though it 'moves' inside my head and I feel very spaced out and more unreal when this happens. At the same time I have times of feeling immensely vacant in my brain and then can get a type of myoclonus - arms or torso flinging out or large jerks. I am conscious throughout this and can speak if spoken to or even get up and move around - which seems to stop it from happening.
I mentioned the brain 'moving' issue with feeling vacant to an M.E specialist and they had NO IDEA what I was talking about. I also have a headache most of the time.
Aerose - the time you talk about suffering the severe anxiety for two years I can very much relate to - I was shocked to read of someone else having this kind of experience, which for me can only be described as a literal living hell. I was given an SSRI at the beginning of my severe relapse in 2009. After just one dose I was so confused I spent the whole afternoon standing in the middle of the room, trying to work something out... I don't even know what. The GP convinced me to take another dose, after which I started to suffer from the most extreme agitation I have ever experienced or seen in anyone. I also suffered extreme suicidal ideation.
I didn't take another dose and the GP said the drug would be out of my system and I would be fine within 24 hours - it took two years for the agitation and extreme anxiety to subside. During this time I lost an enormous amount of weight and worsened my M.E by never being able to really relax. My goal at one point was just to be able to feel relaxed enough to eat a meal with my family.
I was hysterical and crying a lot of this time as I was being tortured so much. I was afraid to be alone. afraid to be with people. My GP was not interested in this reaction or in helping me - he gave me benzos, which I was too afraid to take because for a fear of withdrawal syndrome.
Sorry for such long post. I do believe using the term dementia is fine. That is how I feel at times. My husband keeps telling me 'why did you do that' or 'why do you keep putting that there' and I have no idea what he is talking about. I have lost whole chunks of my life and have very limited ability nowadays to accurately reflect lengths of time. In my mind anything in the past 2 years is recent. anything from the past few months will be 'this week or last week'. My family just laugh at me, but it is a worry.
Last thought - I have posted about this elsewhere but have had a distressing experience of waking at night and not knowing where, who or what I am. I mean actually not knowing what a human is - what the earth is or what being 'sentient' and alive means. I am completely awake when this happens - not half asleep as in sleep arousal disorder. I recall it happening the next day.
Brian well and truly hurting now... gotta go. Hoping to get tested for Lyme properly soon.
