Weird but tired

I've been so tired and busy these days.It really feels good to be this busy sometimes. But I'm Feeling so tired and dont have any energy at all today. Anyways, I'm spending most of my time working toward my choice of going into social work. Some people just give me so much hope while others just scare the crap outta me. I'm still firm on my choice because I can feel it in me that I do want to do this but the uncertainity of whats going to happen and not knowing if Im going to get into the program and getting left in the middle of business mgt program scares me. Top all of this off with dads pressure of graduating etc. Oh well I think I still want to goahead with my choice, its like taking the subway. When the train gives its bell, indicating its closing the doors and u have a nano second to jump in or miss that darn train forever. What are you gonna do?
