I need some advice about my family. Please?

This might be long, i'm sorry. I will try and make it short.

I have 3 siblings so when I ask your advice on this I'll just name them siblings 1,2 and 3. 3 being the oldest. When I was 16 my dad died. sisters 2 and 3 took what my dad owned and kept it, leaving my younger sister (1) and I with plastic rosary. I don't have any photo of his parents, or him at all. When I was 18 my mom died and again sisters 2 and 3 took it upon themselves, took everything of value, either sold it and kept the money or kept the memorabilia type of things, again sister 1 and I were left with an empty house, $20.00 and a choice to either stay their and be homeless or go with one of the older sisters and pay them rent. by this time little sister and I were 16 and 18 years old and this took place a week after she died. Well now i'm 23 and my grandma just passed away a week ago today. This was the last person keeping us together, this was the last person who held the last remaining pictures of my family. A day before her dead my grandmothers niece had the nerve to come to her house and stake claims on these very albums. My uncle (who was in charge of estate) said I could have them. They day of her funeral my grandma's niece again staked claims on these photo albums and took them...........my uncle doesn't care and doesn't care about them in the first place, sisters 2 and 3 are only worried about the valuable items and i've been called some pretty hurt full things over the past week and no one seems to care that I lost out on those photos. I have a huge void and hole in my heart. I have nothing to show my future kids what their grandma looked like, or the achievements of their great grandma, in less than a week I lost the family history, the pictures, the things that meant something to me. I feel like i'm going crazy cause their isn't anything I can do. She didn't have a right to take those. I guess I just feel really lonely. I don't even have any of my grandma now................ I have no idea how to get over this or how to get my mind off of this. I don't know if anyone out their has ever gone through anything like this but I would like some advice on how to deal with this please. How do I deal with the anger, the pain and the frustration? Their was a LOT that happened during the past six years and I wrote as little as possible as to not bore anyone. Please keep in mind I have no photos of my parents, my grandparents on both sides and non of me. The only one's I have are recent ones from the past 3 years of myself.
