Hi Kathy,
I'm sorry for your loss. I have been dealing with feelings like this too. Before my grandmother died in January eight months prior my great uncle (who was like a grandfather to me) passed away, my mom was diagnosed with stage 4 breast cancer and a friend of mine who was helping me work on my faith issues moved away and my faith slipped again. I was taking blow after blow and I did fall into a depression and with that I started to push back my grief and not deal with it because I thought "if I can block the grief and the pain I will get better". Then my grandmother got sick and died in January. Since then I have been dealing with "is this my grief or am I depressed or is it both? Am I losing my mind?". Like you all I want to do is sleep and when night comes I don't want to sleep because I feel like I can't let go of this day because I made it to the end and nothing bad happened and if I fall asleep and start a new day something bad might happen and I might not make it through. I made the mistake of not talking to anyone - not friends, family or even a therapist. I applaud you for seeking help as where I did not and I regret it every night when I cry. I didn't want anyone to see me as being weak so I mask it a lot. The only thing I can tell you is keep seeking help and try - even if it hurts and you break down a lot - to keep going and try and remember that your dad wouldn't want your life to come to a halt. I hope that helps. You really aren't alone. This is the first time I have told anyone how I have been feeling for the last 8 months.
