Sadly no where near Leeds, but this is a useful place to visit so that you can be aware that you are not alone with this stuff. Being scared makes sense when new bad stuff happens, just try not to let it become constant. I am not being flippant and I have been terrified many times, but have been a bit of a techie boy about it. I try to break things down into little groups. Like : Stuff I can deal with
Stuff I will understand with a bit of research.
Stuff I need help with.
Stuff I can do nothing about so try not to worry about.
Make up your own criteria and then start to either knock off the easy stuff or start a plan to deal with the tougher bits. It also helps to have a good team. These can be friends and family or medical professionals. Generally much better than Dr Google which can be very negative as well as useful, so you need to be smart with it. One aspect that I am still trying to master after more than 30 years with MS is listening to my body and knowing what might happen when I choose to ignore it. I might crack it in another 30 years but I doubt it ! Good luck
