lucky you sound just like my SIL when my brother went into a dementia care home. I think it could be grief in some way. Your DH is still with you but not at home where you are used to him being and all the stress you had has wiped you out. Also I think you were running on adrenaline which has now dropped. Now is the time to be kind to yourself if you can. You have done your best and you need to stop blaming yourself for letting your DH down (which you haven’t). You are tired lucky worn out. You need rest 
I suppose I shouldn’t have been annoyed, but…
Engagement Party and then Hen Party
