Rough few days

Just realized 10 days and it will be 3 years since we lost little mouse. I have been thinking about how our lives have changed over the last 5 years- dh and I had a talk and he thinks that I should be able to move on by now- get on with my life. Trust me I have tried very hard to 'move on' but to be honest it is hard when my heart is shattered. I want to be happy, I want to think about my life and be happy with what I have accomplished- I should be proud- but all I can think of is what I have lost, what I will never have. I feel like I have let my family down- I don't feel like I have anyone to talk to about any of this because I feel guilty that I have this much pain- I don't want people to feel bad for me- I don't want them to feel guilty. One of my really good friends just told me that she is thinking of having a baby in the next year- and wants me to be a part of its life. When she told me this I had an overwhelming sense of jealously- and I don't want to be like that- I want to be happy for her, I am happy for her, really I am- but I want it and I can't. Dh says that I should talk to her to tell how I feel, but I feel like this is my problem- why should I make it hers. I don't want her to feel guilty, I know she told me because she is happy and wants me to be happy to. I just wish that time really did heal wounds- because right now I feel like it is a big lie- every time I think that something gets easier or better- I fall apart and feel like it happened yesterday. When does it get easier?
