Dear Natural, I think that what you are going through is a natural part of loosing your sister. After my Mom passed, there were a lot of unresolved issues. It took my sister and I almost a year to even start putting our lives back together. We had to force ourselves to sew for 5 minutes at a time. We then concentrated on forcing outselves to do more. It has now been 2 1/2 years and we are pretty much back to as normal as we are going to get. Give yourself some time. Things will come around. Be kind to yourself, this, too, will pass. You are in my thoughts and prayers.
