I am so sorry to hear what you have been going through. My husband constantly is looking for things or asking me when we are going home (we are home) or when we are going out. I find the best way to handle this is to agree with him. Most of my answers consist of "later, I'm a bit tired right now" or "that's a good idea. We'll do it later". He usually forgets when it is later. Just an idea....... Is your husband a veteran? They do have some benefits you might want to look into. We live in the U.S. and for example my husband gets a discount on his day care.
I will be thinking of you and hoping today is better.
