Could someone pray....

I am just divorced, living back at my mothers. My sister has depression and I have 2 small children.  I am working from home, and things are going from okay to bad now. My sister stays in this house all the time. She is 43, never been married, no friends, seems to be very angry at the world.  She says she is a christian but I am having some troublle understanding how she is so angry.  She goes from church to church and then complains about the people there. She states they are not friendly. I think she has a personality disorder on top of her depression.  We were sort of ignored emotionally growing up..it was like every man for himself.  She never left this house and never extends herself into the real world.  I am needing some prayer for her and for myself, I need to find a place to live with my boys.  It's overwhelming living back here with her and also my mother is sick with cancer. I am here for my mother, but I really would love to find a place of our own, somewhere nearby.  My mother also has depression but doesn't acknowledge this..so that is also a challenge for all of us.  I know times are tight for all of us and I shouldn't be complaining, but this has been ongoing for the last year and I am so desperate I thought I would post.  My ex hasn't paid child support, but just got a job and I should be getting help soon with that. Thank you for your prayers, whoever reads this.
