How do I get over the fury concerning the passing of my mother?

My mother passed away about two weeks ago,and the pain of it is rather substantial.I don't want to do anything...its a task to even get up throughout the day.I'm trying to not isolate myself but it's proving to be extremely difficult.In addition to the pain of it all,I'm experiencing a tremendous amount of anger in regards to her death.Its not just anger...its rage. My mum wasn't the healthiest person,and the latter part of her life was a series of disappointments,failures and health scares and concerns.I visited her in February and I was shocked at how quickly her health had diminished since I last saw her.There's so much more to this story,but I will leave it at that.I just don't know how to get over the rage I feel everyday concerning it. Also,i just feel like I don't want to be bothered by anyone.

I feel as though she left me here...I'm parent-less.I Just don't know what to do with myself anymore.In February,i turned 27.I dunno...i just thought I had more time with her...
