I want to get a job

I have heard Brooke say not to leave a job because you’re unhappy. I’m assuming this applies to the job of stay-at-home mom as well? For 7+ years I have been home with my kids (7, 4, 2) and I am just tired of it. I don’t feel fulfilled, and I really want to get a job outside the home to give myself a new challenge (although I feel like I’m failing at the current challenge). I’ve been dealing with lots of mental health issues due to hormonal imbalances for 3+ years since getting pregnant with my last baby, and I just want to escape my life, and getting a job seems like a way to find something I can excel at while getting a breather from the chaos of my reality at home. Where do I begin to deal with this?
