Getting sick, not eating... all I do I is worry. Ughhhh

To be clear, it’s my 14m old sons first time in daycare, he’s been in for about 2 weeks now. The adjustment has been rough for both my son and I. He’s teething and getting sick which has impacted his mood and him not eating at daycare. The situation is stressful for me because I’ve been over thinking. Im fine now. I’m choosing to stay positive. If you’re a mother, you may not relate to this specific situation but there has been or will be a time where you worry til your freaking head hurts. Lol that’s what just happened to me.
