Hey, I'm so sorry to hear about your dad. I lost mine 20 months ago and have been where you are. I was pregnant with his first grandchild at the time who came along 2 weeks after he went to sleep (I was 31).
 

I'm not entirely sure that I have any advice, but I do know one thing. You only have your dad once, you won't get this time back ever. Do you live with him or still see him because of Covid? If you do please please spend as much time with him as you can, I did and still it wasn't enough and wish I could go back every single day. 
 

Are you working from home? I do remember being in the office and just breaking down, one minute you're busy and you almost forgot (If that's even possible) and the next it hits you again. 
I suffered terribly with anticipatory grief, the anxiety of not knowing how or when it would eventually happen and the moment it did that went away. 
Your work sound understanding and so they should be, concentrate as best you can, take time when you can and just get through one day at a time.

if you're wfh then make sure you get out for fresh air as well, these times are depressing enough as it is let alone dealing with something as hard as this.  
 

I still maintain if you haven't been through this you have absolutely no idea how it feels, you can't even imagine. 
 

Sorry I went off on a tangent there, but I'm sending hugs.
