when is it appropriate to leave home with newborn

Tia
Although this is my second child, with my first I suffered with postpartum depression and  did not come out of my room (other than to get food from the fridge ) for nearly 2months. To avoid such happening I frequently walk when my husband gets home and just take a drive at random without babygirl. I want to get back out already I feel great , being in the house is starting to weigh in on me and I can feel myself  becoming  extremely edgy and emotional all over again.
