Teddy: Your feelings are very normal. We've all been there. The first of everything was SO tough. And even some subsequent years. I remember second Christmas SO vividly. But it does get easier. Time really does heal all wounds. We might never forget but we do learn somehow to forgive and move forward. I had the toughest time with that. I was a SLOW learner.
Take comfort in the fact that it is really true that each year gets a little easier and you detach more.
Do something nice for yourself tonight - movie, glass of wine - bubble bath - whatever you enjoy the most.
