feeling sorry for everything

Its amazing to me my son has 4 adult men in our family and not one of them can step up and make a commitment to him to come spend one day with him every couple weeks. I understand people have lives and things. Important things. But my son lost the most important man in his life and wouldn't it be best for a close family member to come and try to fill a small bit of that void for him. No. Instead I have to contact Big Brothers Big Sisters to try and match him up with a total stranger. I just feel so angry about that. No one asks me to do anything anymore. Found out some relatives are going to a festival. No one even thought to say "Hey, ya wanna come?" Then when I invite people somewhere they all say No. I have plans already. Im tired of being starved for company. Yes. I still get sad, depressed, upset, cry. But that doesnt mean I dont want to go do something once in awhile with someone other than my parents. I feel like people have just forgotten him already. People ask to buy his things. That started a month or so after he died. I don't get people. Was I like that before he died? So insensitive to others feelings? I just want things to go back to the way they were.
