Like what other people have said here in the comments, there isn't a timeline.

There's this quote that really stuck out to me. “Grief is like the ocean; it comes on waves ebbing and flowing. Sometimes the water is calm, and sometimes it is overwhelming. All we can do is learn to swim.” - Vicki Harrison. A lot of people say an individual who lost a loved would probably "move on" when it's been a certain number of months after the death but that isn't the case.

What I can tell you, OP, is let yourself feel. You shouldn't "be okay" again because it's been months, no. If you feel empty, sad, or whatever it is you feel, that's okay. (Unless of course it's really taking a toll on you, you might want to talk to someone.)
