Phase Three Frustration

I really am starting to feel like I am going to be on Phase 3 forever! It has been decided, again, that I will be going on another week of this. The last 3 minute run is just not working out for me, and I need to build up that strength before I can move forward. I can see this taking till after spring break, and although I hope not, I will be okay with that. What I would really like to do is be on phase 4 by next week so that way I can do it before and after break...because I still am unsure how I am going to run during. Most importantly I am not going to let myself be discouraged because it is only that last three minutes and I am definably improving!
