Hey Jen67,
I understand. My son first went to uni at 19 and came home after four weeks saying he wasn't ready and wanted to earn some money and learn to cook. To say I wasn't concerned is an understatement. But, he went to work and he finally went back to uni at 24. He did a lot of thinking. He met some great people there and is still friends with them. He is 30 next year and I am proud. He isn't married but dates and has a job he enjoys and lives in Japan. Obviously I can't see him but we talk frequently. Being so far away kills me, but I know he's ok. It's so, so hard letting them go. Don't worry about him settling, he's in school, he needs to do this now. It may even change, again. Everyone is different. He will need your love and support. Whatever he does, just be there for him. It'll all be good. I hope this helps. You're a mom, you'll be just fine. Plus we're all on here for you too. xx
