Mother-in-law has moved to facility, and now I just feel numb to everything. Any advice?

Hello, a while back I shared how my wife and I were dealing with her mom’s declining health as a result of frontaltemporal dementia. The advice was overwhelmingly helpful. This week, after months and months of precipitous decline, we moved her into a great facility. But now that our roles as caretakers are different and largely off our plates, I just feel numb. I don’t know what to do with myself without all the myriad caregiver tasks that we had absorbed into our daily existence. I can’t clear my head from the persistent awareness of another person with a severe disability needing something at any minute. I have a lot that I could throw myself into. I’m in law school, I have two wonderful kids, and finally the time with my wife where we can just be us. But I just want to do nothing, and I don’t know how to find the energy to help my wife navigate the feelings of grief, guilt, sadness, anger, and loss that come with a loved one moving on in this way. I absolutely want to be there and I’m trying, but as I said, I just feel like a person walking through a silent movie now. Until she moved, my mother in law lived in an apartment that is the bottom floor of our house. Our front door has a large glass pane in it, and her method of communicating that she needed something was to stand at the door and press her face up against the glass. It was at first frustrating; then accepting. Now, I’ve realized I have an involuntary habit of looking at the door whenever I pass to see if she’s there needing something. All I ever wanted it seemed was to have my house back from this sense of constant need and imposition. Now I find myself looking at the door and seeing nothing and thinking, without that urgency looking in at me, I don’t know what to do. And I realized I became so used to it that now, in its absence, I miss it.
