Sister, Mom, Husband - Need

I saw Shutter Island with my friends tonight. Leaving in the car I cried for my sister and what I have lost with her due to her mental illness that did not occur until her late 20s. Then I felt such a longing for my mom. My life is in a lot of turmoil with major decisions required and soon to face substantial personal losses. I have been under extreme stress for six years and the grief for my husband was only the beginning. If I cannot have a husband to comfort me and provide me guidance it would be nice to have a sister which leads me to really needing my mommy.
