You seem to be taking care of yourself and understand that parenting is not something you do to perfection. You are likely eating and sleeping pretty well and connecting with others regularly.
Since you seem to be in balance right now, you may want to take a few minutes to think about whatever small areas in your life could use more attention--maybe your relationship, exercise or your career--and make time for it. Keep up the positive self care, it is good for you and your family!
Your responses seem to indicate that you are experiencing stress that may be impacting your self care, your relationships and/or your decision making. While you may not be experiencing burnout (yet), you are at risk and this requires your attention.
You are likely experiencing Burnout. This means that you may be suffering from chronic physical and emotional exhaustion that may lead you to believe that you are not effective in your role anymore (as a mother or professional). You may be feeling deflated, hopeless or sad. Your mood may be irritable and you may find yourself crying, avoiding people or feeling angry.
Seeking out support, whether professionally or personally is advised. This prolonged state of stress is not good for your overall mental and physical and health. You deserve to spend time taking care of you--you are worthy of your own time, love and attention.
