Happy Belated Birthday! I'm glad your oldest daughter stepped up to the plate and did something nice for your birthday. Yes, she's growing up (finally). You have a number of surprises yesterday and it made your day much brighter for you.
You've come a long way in the last 12 months and I hope that things will settle down for you in the near future.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
