Renegrademothering.com- therapy during holiday stress

I am having trouble staying asleep tonight. I feel holiday stress, when researching holiday stress, stress and cancer, what causes holiday stress, etc. I found the website renegrademothering.com. I laughed to myself really hard, quietly though since I am holding up my sick son who is breathing heavily. I regret now having him sing at the senior home, I regret not pulling him out of school the last week of school, I regret not giving him more vitamin c! Being a mom, teacher, caregiver causes intense worry, fully, regret, etc. How can I laugh more, judge less, create fun, not perfection?
