I can empathize with how you feel. I lost my 7 1/2 old lab 9 weeks tomorrow. I work full time, have 2 toddlers, a husband, dog and cat. My life is busy. I catch myself not thinking about Kasey and I feel guilty. However, when he was alive, I could go without thinking about him all day too, so it really isn't a change. However, when I do take the time and let myself think about him, I can become a wreck all over again. I miss him so much and wish he were back with us.
I think it'll just take more time. I wish I could just think about him, picture him, dream of him, but I can't. I agree, memories arent enugh for me either. Maybe that would be too painful. I still cry for him whenever I let myself think about him - like right now.

I find myself still feeling the guilt of not realizing he was sick and trying to do something for him. I've realized that the grief process is so very different for each person that there is no "normal."
I'm sorry for your loss.
