Like others have said, I recommend assessing what you need before doing anything or not doing anything. I know it sounds like a no-brainer, but a lot of people dealing with grief don't take a moment, step back, and think "what do I need?" It also changes from moment to moment as we advance through the stages of grief.
I'm not going to lie, because some things you never get over. They just get easier to push back and not think about and not have to deal with right that moment. They still hurt, maybe not as much as they did, and they can still get the feeling refreshed.
Speaking personally, I'm the kind of person who needs time to deal with things gradually. If I try to deal with it all at once, I become quickly overwhelmed and just shut myself up inside, a ball of anxiety and depression and more or less shut off from the world around me. I literally need distractions so that I can deal with grief and upset, little by little.
When my partner of several years died suddenly in 2007, I felt completely lost, out to sea, adrift and unable to deal with it. I decided that I needed to focus on my creative career and process, and deal with the loss when I felt like I could. When those times came, I put everything aside and dealt with it. In this way, I was able to get myself to a functional state. But it was a very unsteady progression; sometimes I'd be working, not thinking much, for days, and then I'd hit a wall, and I'd have to deal with some feelings or thoughts or memories or some nebulous sadness that hit like a freight train. It was also the time that I learned -- perhaps exacerbated by the grief and the loss -- that I have severe anxiety. Before that point, I had never thought about it as something that was a part of my life or that I ever had to deal with. Fortunately, it's much better now, but for years it was a daily struggle.
It is something where we all have to take one step at a time, one day at a time, and sometimes it is a fight every day just to get through. I find that creating is helpful. Honestly, my most successful and longest-running work, Incubus Tales, was begun just over half a year after my loss. It was still in that year though, so a couple of years ago when it was coming to an end, I had to deal with those feelings -- I felt like I was closing the book on my last real link to that year, that time, and him. It was hard to do, but I did bring it to an end that I could be happy with (and might pick up again later!)
The most important thing is to figure out what you need, most of all, and then what you want, and what will help you get to where you'll be okay, even if only for the moment. There is absolutely nothing wrong with taking as much time, space, and everything else as you need. If creating doesn't help you, then take some time off from that. You don't want to make it worse, and it is the hardest thing any of us ever has to deal with.
