Steal My Joy

Do you know the song Old Church Choir by Zach Williams?  I hear this song all the time and I love it.  For about two days now there is one line from that song that has been stuck in my head: There ain't nothing gonna steal my joy.  No there ain't nothing gonna steal my joy.  I have realized that God is trying to tell me something.  God is trying to show me how often and how many different people I let steal my joy all the time.  The wonderful joy that I feel when singing about Him alone in my car.  The joy that I feel because of the wonderful children He blessed me with.  So many times a day I let people steal my joy.  Between some of life circumstances that come up and some of the students that I teach I let them steal the joy from my heart.  I let this profession, where I go in all day just trying to do what I can to put a band aid on a system that is broken, beat me down.  I let these students taking out their other issues on me take away pieces of me.  Sometimes I let all the burdens that come with having two little ones, working full time, and being married to a football coach steal away little pieces of my joy.  Sometimes my heart feels so heavy because I have given up so many pieces that I don't have any left.  I know that the big answer to this is that I just have to rely on God and He will project the joy in my life and exude it out of my heart.  I know that I need to trust and rely.  That always seems to be the big answer.  The problem with that is that I don't know that next right step to take.  I don't know what it is that I need to be doing in order to be able to truly trust and let go. 
I have gone my whole life thinking that I needed to be self sufficient and that they only person I could truly rely on was myself.  Now I am slowly learning that I cannot rely on me.  That I can't do it.  God always wanted me to know that I can't do it.  How do I overcome years of conditioning telling me that I'm the only one?  What is the one next step?  I know what the problem is, but where do I go from here and how do I start to fix it?  Maybe one day I will figure it out.
