Tsuki, we grieve in different ways. You are angry cause you lost your mom, your anchor. Let the anger out. Cry when you need it for they are poison leaving the soul. And i recommend writing daily in a journal of all that you are feeling. In a years time read it and see the growth you have gone through. I lost my dad 3 years ago. Still fresh and painful. Don't let others tell you to get over it, that is cruel. You take the time to process what you need and to make peace with yourself. Forgive yourself where you feel you need to and her where you need to. That is called unfinished business. You then can heal and move forward. Blessings and tc
