@aliali Please excuse me for answering these same questions. Yes, I have been diagnosed with depression, and have had both medications and talk therapy. Really, grief takes as long as it takes, I don't know that you can put a timeframe on it. And in the near future, you might be having a good day, then something may trigger a memory of your father, causing sadness or grief for a short moment. It's all okay, and to be expected. I don't believe emotions [Good or bad, positive or negative] can be assigned a definite timeline. That's my opinion.
