Definitely Miss Fourth of July. I have a daughter with autism and that song sums up all the feelings of the time when we got her diagnosis. It was 7 years ago but that song brings back such strong memories every time I hear it. Not very many people I meet can understand what a family dealing with autism goes through and this song, although written about something totally different, just hits home unbelievably.
When I'm having a stressful day, I listen to that song and then to Welcome to Wherever you are and I look at all the accomplishments she has made and where we are now as opposed to then and it cheers me up. It truly is great therapy. (Sorry so "corny" but that's just me)
