My Spanish Needs Refreshing

Today I went to a meeting for the mission trip I am going on to Guatemala in July. We had a short Spanish class after the meeting. I knew that I was not good at Spanish especially considering the years of Spanish classes and being surrounded by Hispanic families in my daily life. Today I realized not only am I horrible at speaking and understanding Spanish, but I have also lost my vocabulary. I need a refresher on vocab so that at least I have some single words to use even if I don't have any sentences. Wish me luck.
