I went through two and a half months at the start of the year when I was overwhelmed with grief and emptiness. I lost almost 20 lbs, couldn't go to work, most days I'd nothing--didn't read, watch TV, talk to anyone, even listen to music. Both my cats had died. I wasn't suicidal, I was ... Nothing. Numb. Empty. I had a poster that I hung in my bedroom where I could see it from my bed:

I sat with the feelings, or lack of feelings. Day after day. Gradually the feelings of life returned and I didn't feel empty any more.
I was fortunate that my situation allowed me to take the time I needed. It was a healthy way to deal with the pain and recovery. As much as you can, ItsJustMe, I'd say stay with your feelings & let the be as long as they need to be. That way, when they leave, chances are they'll stay gone longer.
Take best care.
