Big Decision Overwhelm/help Getting Unstuck

I’m a mom of 2 small kids and have been working full time a job I don’t feel aligned with but feel it is golden handcuffs.  Good pay and car etc.  But I really want to be home with my kids while I have the change and my life balance is struggling like my marriage and sanity because I’m so burnt out and over stressed.  I’m scared to quit my job, but my husband is in agreement that it is probably the best step forward for our family.  I struggle with decision making and overwhelm and analysis paralysis.  How do I approach a big decision like this?  How do you gain clarity and confidence in a decision?  I’ve tried changing my thoughts about the job and circumstances and it works for a short time and then I’m back to burnt out exhausted and crying breakdown.  How do I get unstuck?
