How to spend my day

My ex broke up with me nine months ago and I've been finally getting on to moving on from him and accepting that that chapter in my life is closed. However, the day that would have been our 2 year anniversary is coming up and I'm a little nervous because I don't know how I'll feel that day. I don't know if I'll be sad and mopey or nostalgic or if it will just feel like any other day. But I do want to do something special for myself so it takes the bittersweetness away. What did you do on your would-be anniversary to take your mind off of the significance or the memories associated with it?
