sad

My daughter left today to go home to her family who miss and need her.  She lives 7 hours away.  I have not ben alone since my husband died 4 weeks ago.  I have two other daughters who also have been coming in.  I'm not a weak woman but I am having such a hard time.  I am afraid of making any plans.   I know that I need to find some help in dealing with this because I cannot do it on my own.  Will it get any better?
