How do I keep my dog from barking when I'm leaving the house?

If she is making a fuss and you come back- to comfort her, whatever, she's learning that at some point, when she does enough, it works to get you back! So, she'll keep doing it every time. In nature, dogs generally stay in their packs most or all the time. What would make sense to her is to be really tired when it's time for you to leave. Then, it would only make sense for her to stay behind, in her mind. Take her on a long walk/jog in the morning. Maybe even teach her to jog on a treadmill. Maybe you can have a certain toy she only gets to have when you leave. Maybe buy one of those toys that you squirt the food inside? Let her smell it, tell her to sit and stay, give it to her, and leave. You are the leader. Leave with confidence. If you're uncertain, she'll use that against you in one way or another. At other times, do regular discipline and exercise with her. The most balanced she is, the less likely she'll have problems like this. Best of luck!!! :)

she needs a male friend to occupy her while your gone.
