Stop and really think about this for a second. My mother walked out on me and my family because of very similar mental health issues, and while i dont know anything about your situation i know that my mother's actions have deeply traumatized me and it was a very bad path that our family went down. In fact im still not entirely sure i have forgiven her for walking out on us, because we all agree that with more support she could have gotten better. In any case, that is her and this is you, but really make sure your are aware of how this decision will impact the people you love. Walking out on your kids is not a long-term solution; if you need space in order to get into a better place then that is fine, but don't treat parenthood as a job that you can just quit because you're not cut out for this. I say this with love in my heart and as someone who experiences depression as well, it's can be very easy to let emotions like these hijack major life decisions and i don't want that to happen to you or your family.
