Disease modifying drugs decision-making

Been referred to addenbrooks to see the consultants there and discuss Dmd I really don't know what to do, So worried that it will close my world up due to avoiding catching things and how it will effect my immune system! But then the flip side i have no idea what My Ms will be up to This resulted from a admission in may not being able to walk properly and left me with some extra tingles and weakness Any wise words out there I am so muddled
