Hi firstly don’t make any sudden changes. All will become clearer. As a lone mum of two when I was diagnosed I immediately went into doom doomed doomed but actually I wasn’t and it’s been OK. Even if it is worst case scenario you will be ok and he will be ok.
As UK based MSer I like https://multiple-sclerosis-research.org/ive-just-been-diagnosed/ Barts MS centre blog. It’s a bit technical sometimes but they know and they are at the forefront of treatment in the UK.
Self care is the key.
All the best StrictlySoca
