My heart goes out to you Kujacker. I must admit the tears were flowing as I read what happened with your Mom. I lost mine last year, and it is awful for all those left behind.
Someone mentioned the stress of going through a lawsuit; and speaking from experience, they are right. It is a horrible experience. It will not allow you time to grieve and for that grief to lessen; salt will be rubbed in your wounds every minute for the years and years that lawsuit drags on. The emotional toll is staggering.
If you find a lawyer to take your case, I hope that knowing this will help prepare you and make it easier to bear.
