I would go to the party and have fun. Hold your head up high, back straight and put a smile on your face and just be yourself. There will be so many people there, that the ow and her boyfriend will be nothing but gnats.

A job would be a nice way to get out of the house and become even more independent and have money of your own. It's a nice way to meet people and a change of scenery. Good luck!

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.
