I heard that God takes into consideration the person's mental illness before they committed suicide. So sad to hear this. I hope you have faith to know she is okay. I recommend going to chapels of Catholic Churches where Jesus' presence is said to be and just talk to him about it. I suggested a friend come with me one time about her struggles from moving away from her family but doing what in her heart she thought was right and she had to leave the chapel because she swelled up with emotion. I really feel its a healing place. When I am literally drained by life and just tired of it I go there and leave feeling refreshed and in peace again. May God hearken to your prayers and bless your family.
