Emily,
I am the police and have dealt with taking my own sons (two of them) to court, followed one of them to his dealer and arrested him, went to court and visited prisons in three states, and now have to visit one at his grave.
My suggestion is that you take a free day and use it doing something for you. Never miss the chance to tell your son/daughter you love them, but start taking care of you. Good luck and God bless.
