DS turned 18 on Friday, felt on a high, we had the best gathering we could for him during partial lockdown, his family and friends came at various time-allotted slots and it was great. But now I feel a bit sad and empty. I am thrilled for him that he has a direction in life, etc, but worry how life will be when he leaves home in September. He is only child and we generally have a great relationship, lots of fun and laughter. How do I cope when I am left with grumpy DH?!
