I am so sorry for your loss. I can kind of relate as today would have been my dad's 74th birthday. I've been feeling a little melancholy even though it has been 2.5 yrs since his passing. What you are feeling and going through IS grief, which sounds to have you going through a bit of depression. You sound ok to me, just trying to figure out how to adjust to your dad's absence. I am not a proponent of "time heals all wounds" because it hasn't really worked for me. I found it's more about moving through grief to the acceptance of what is and adjusting to the change. Small steps can help you keep moving forward in this transition time. Try to stay out of bed a little longer each day, look for joy in what's around you, take walks and really notice your surroundings, yoga, meditation, soothing music, etc. I don't mean to sound trite, but we sometimes have to make ourselves do the everyday necessities to help re-adjust to a routine. 62 days is not that long ago, so try not to be too hard on yourself.
