Hello @MrsM
Welcome to the forum.
sorry you have had a reason to join us.
Everything you have said is very common sadly
You may find the welcome post tap the blue text is helpful
The anxiety you report is very normal. Having a reason for the stroke is comforting when it is aligned to the medications that you’re seeing delivered -in the meantime you will have to trust that the medical folk have done the right things and are giving you both the right advice. they’re good on the acute care - not so good on the chronic long-term (resource challenges and the lack of a visceral understanding what it is like to live with the after effects) 
The Magnifying glass above is a very good way of finding the masses of previous posts relevant. Asking questions will always get a reply but searching for previous discussion will generally reveal much much more. Including topic like "don’t you look well” (”thank you. I’m not ill, my brain has been permanently damaged so I suffer with fatigue and cognition and emotional and very many other invisible challenges constantly”)
Please also get support for yourself it’s very challenging to be a carer. It that you have a marathon not a sprint so saving energy, etc emotional reserves etc for next year is important. Also encourage your husband to rest. My wife just had a giggle because she can’t do it to me but the more he rests the more of his energy will be spent recovering what you cannot see (and for @BakersBunny I’m three and a half years not three weeks post stroke!!)
