Hey there! I'm 21 so we are pretty much the same age, and I understand all the stresses that school can bring!
Good luck on reaching your goals. You CAN definitely do it!
I recommended though what someone else mentioned about not weighing yourself EVERY day. Weight really does fluctuate daily, and there are so many factors that can affect it. I weigh myself every Thursday morning as soon as I wake up, and that has been working out great for me.
Your outfits for your bday and Christmas sound great by the way!
Anyway I'll try to keep up with your journal and help you stay motivated!!! Good luck
