Girl girl girl, i am so sorry you are feeling down. I do agree with Judy's post, deleting pictures, and emails wont wipe out any memories. Angie, try to file those emails, and pictures in a hotmail file, or yahoo, or something, thats what i did years ago, as i had to go thru a similar experience, i made a little file, gave it a name, and closed it, till i was ready to open it, and look at it again. It helps not having to see it everytime you open your mailbox, yet comforting to know they there when you want to see them.
Hope you will feel better soon, and hugs to you!
