When my grandmother passed away I hardly cried, if I cried at all. I was sort of on autopilot. Then about two months later somebody asked me something about growing a plant. I thought, "Nanny would know. I'll call her." It was after I had already picked up the phone and started dialing before it hit me. I stood there at work crying my eyes out.
Sometimes it just takes time to process all the emotions. You shouldn't force try to force them or expect anything from them. You will find your path in your time. You haven't had it easy and that makes it all more complex and will most likely take more time t sort out.
Other than not crying are you doing alright?
