Be careful on that thought that your depression is gone. If you need to cry please do so. Do not hold back. Grieving the loss of a relationship has many stages. You can share this with yourself or a good trusted friend and us. Do not hid from it.
But keep up the happy all the time with exceptions of course:)
Your doing well.
