Hi Gemma
Your symptoms sound quite typical I think for fnd. I started falling/tripping up and was having joint pains. I suddenly developed left sided facial spasms which then spread across my entire face. It's natural to find it distressing when you suddenly experience these symptoms.
I had a period of 5 weeks in hospital and suffered with multiple seizure but was alert and aware. I also lost my ability to talk at times and my eyes would shut and not open for hours.
I take sertraline and after four months returned to work. I sometimes have relapses but staying positive is key.
Try mediation, pacing your day, getting proper sleep, avoid alcohol. I practised talking and singing to strengthen my speach. Try mental challenges to keep your brain active. If one side of your body is numb or twitching make purposeful movements with the other side of your body.
Hope this helps x
