Beyond Blue,
I too struggled when I was first diagnosed with DID. I don't think I have ever had a major problem with losing time.
I also denied that I had DID....... well part of me did. But I couldn't explain the the other voices (parts) that came out, I got pushed into the background.
When I was growing up people kept telling that nothing was wrong... but I knew something was wrong.
It doesn't change who you are. DID is the intelligent brain trying to protect itself from trauma.
Try and relax. Like the others have said be gentle with yourself.
