Hi,
Im so very sorry for the person you have lost. This is a very big part of your life. It is so hard to let go. I lost an uncle to pancreatic cancer, a mother in law to breast cancer and a sister to a very hard loss of suicide. No matter what you must be strong and move forward. Take one day at a time. Talk to the person you lost and talk to the family members about her. The good times will eventually come though. She is looking down upon you and expecting the best from you. Dont let her down.
