Should we really argue, if anxiety comes first and then BFS, or vice versa?Stress goes first, and it might be of any kind - hard life/bad schedule, extra sports (I rememebr one fellow twitcher saying he was doing 3 or 4 workouts per week, and the rest of days he was running 5 miles per day or swimming equally), lazy life, viral infection, maternity (and being a young father too!), wrong diet for many years, emotional sterss, name whatever. I haven't seen yet nobody who would not fit that description here, no matter whether they suffer generalised anxiety (as me), or not. At least, I have well over 35 years of GAD experience (virtually lifelong, and very unpleasant), but only 1 year of BFS... My triggers were definitely 14 hours sitting typing working day for a year, a lot of emotional sterss and a flu. I still needed some strong push to my immune system to make my nerves hyperirriated despite on few decades of constant adrenaline oversupply

))Anxiety "helps' to stay in and makes overall condition worse, but one should not be really a GAD/OCD /whatever similar disease sufferer to get BFS.AFTER getting BFS, almost 100% start to have anxiety disease, more or less prominent, and in fact often the most anxiety striken people demonstrate the most dramatic or fast healing (if they have an experience to live with anxiety disorder, or if they just become decisive enough or have less secondary benefits associated to high anxiety).
