Now the depression appears to be better should we talk about our relationship??

Yes, but gently. Don't push her back into a depression. If she says that she is not ready or does not want to go back, just let it go. She is in a very delicate stage right now. The doctor has just taken her off her medication. There is no way to tell how this will change her. It takes a couple of weeks to a month to get the drug out of your system. Also, the doctor has to ween her off of it or she could become suicidal. You must be supportive, if you really care for her.
