Overwhelming Grief

I am so overwhemed. I lost an adoptive sister to brain cancer a year and three months ago. I saw her pass and it has been difficult but I have been able to move through it in somewhat of a healthy way overtime. Her mom and other sister who were also my family moved accross the country and I have missed them desperately but I think her mom has been trying to cope by seperating. I have done everything I can to keep in contact but she has not been responsive. The last time I spoke to her we talked... Overwhelming Grief
