Stephanie, You don’t need to account for your emotions to anyone. Your mom would want you to be happy even though she is gone. Everyone grieves differently, You will be okay eventually, at least able to live with your grief more comfortably. When you think it is gone and you are not mourning any more, it will on occasion pop up and let you know you are still grieving. So, enjoy your good times and if anyone tells you that you should feel something different from you are feeling , tell them where to go and how to get there.
