Really, if this is your first day at this, get comfortable with the foods you are eating and don't worry so much right now about tracking everything. Some people will tell you the carbs are high, others will focus on caloric count. The more comfortable you become with what you are eating you will reach satiety and naturally not eat as much as you are initially.
Baby steps. You have things to learn. Do not try to learn them all at once!
Positive mental attitude
Believe in yourself.
Like who you are
Never say quit.
If your body is willing, your mind can push it to do some amazing things.
