sad and anxious

Today I am feeling sad and anxious. The sadness never ends but I am feeling anxious because my husband is not here with me and won't be for the rest of the day. I could really use something to calm my nerves...but I don't have anything to take and knowing what I am like...I would probably take too many to calm my nerves.
I guess I am just so used to travelling with him to his jobs that now that he is not around...it is driving me crazy!!
