Anxiety manifesting real symptoms?

[nh_user_1409999]

Hi, I have had health anxiety, general anxiety, OCD and delusional disorder most of my life. However, most recently I have been worrying about having vCJD. I find the idea of this illness terrifying and no matter what I do, I cannot shake this anxiety. I know the chances of having it are extremely rare. Apart from anything, I was born in 2001 (you are only considered at risk if you were born before 1996 in the UK I believe). However, I have managed to convince myself I picked it up whilst on holiday in France around 2006 as their epidemic stretched on longer (even though at that point in time they had restrictions to try and prevent contaminated material entering the food chain). The last 10 weeks or so I have been feeling quite dissociated / zoned out and have been worrying this is the first symptom. I just woke up one morning feeling like this after a night out. I also skmetimes get dizzy when standing up suddenly and get muscle twitches a couple times a day. I sometimes think I am being forgetful / have brain fog as well. I managed to convince myself that I had this illness last year and had similar symptoms without feeling zoned out as frequently. I also just started aripiprazole 10mg properly 4 days ago and since then have felt more anxious / and fatigued than usual. If I manage to have a day where I am less anxious and don't think about the illness these symptoms go away too. I was wondering if anyone else has had experience worrying about this illness / has experience with symptoms being manifested after reading about a particular illness?
