For Freedom Christ has set us Free

As Eric returns from him interview in Richmond and I enjoy a quiet moment while both boys sleep Galations 5.1 replays in my mind- 'For Freedom Christ has set us free; stand firm therefore and do not submit again to a yoke of slavery'
I want to live in freedom. I do not want to be overcome by anything. However, I know that I can start to feel trapped by the expectations that I create for myself. As I decide what the perfect mom/wife/sister/daughter/friend etc looks like I come up with what I think to be a really great person... in fact that person probably is really great but this is not the person that God created me to be, it is the person that I decided I should be.
Why do I fall so quickly for this temptation? I think I'm afraid of the freedom in the alternative. However, the person that I have the freedom to be is what is best. My creation is good but it is hard and burdensome. The other is unknown but free.
Hoping that I can choose that which is best!
