It really does take a couple of months for the fog to lift and then you start feeling the emotions in full. So, you're right on schedule
Relating to your post above, I would caution you to about shoving things out of your mind. Emotions don't always make perfect sense, but they are real and we need to deal with them.
I lost my son 3 years ago. I did feel guilt and I shoved it right out of my head, thinking that it was just a "Moms should always be able to prevent bad things happening" way of torturing myself which I knew I didn't deserve.
But the feelings didn't go away. So, I sat with them awhile. I thought about it. I asked myself, "Is there anyway you are responsible for his death?" No. "Ok, are you feeling guilty because of things done/not done while he was alive?" No, that didn't feel right either.
What it came down to, for me, was guilt that I didn't fall down dead when I heard the news. My beautiful boy was gone, and here I was walking around, making dinner, watching tv. What the heck kind of mom was I anyway??
But when I thought it through (a number of times, over months), I came to the conclusion that I really have no choice. God didn't strike me dead. Throwing myself off a bridge wasn't an option. So, I'm living my life.
A lot of days that didn't feel so good. But over time, as you accept, it gets easier. Smiling today, laughing today, having fun doesn't take anything at all away from my son. But boy, does it it help the son I still have. And that's my most important job now.
Had I continued to ignore those feelings, I don't think I'd be doing so well today.
