I'm glad you are coping with your feelings of loss about the email situation. Feeling sad and depressed about things we lose is hard - it is natural and normal, but hard. Embrace these feelings! You lost something that you enjoyed and liked, and you are grieving for them. Those feelings of loss are not something that you need to 'fix'. This is where you are, and this is what you feel right now, and the feelings are the normal and expected reaction to the loss of something we want or need.

Remember that after the pain comes acceptance, and peace.
