I'm a woman that have been recently dignosed with major depression. I've been feeling very sad all the time and having a lot of stress for almost a year before I realized that I needed medical help. Of course when you start a depression, you just don't run to the doctor's office to get drugs!! Nobody that have depression wants to take medication! When you realize that you're not well, you try to see if it will resolve by itself. Then you try different things to see if it helps like asking for space and spend some time with your ownself to try and listen to your body. Trying to see what are the reasons you feel that way and try to solve them. I'm in a 10 year relationship, we are living together and you know what, I asked my spouse to let me alone and let me deal with my feelings. He can't do anything for me because I'm the only one who can fix my problems. I take meds for the last 3 months and doing therapy and I did all of this by myself and I don't want anybody in my family or my spouse to tell me what to do for my depression. I'm in contol and that is it.
So the only advice I can give you is to let her be. You have sent her some information on depression, that is good and if she needs you, she will tell you. In the mean time, let her know that you will respect her desire to take a break, and that you will stop contacting her so she can have her peace and that you stand by if she ever needs you for anything, you will always be there. Then respect that and have faith in her. She will pull through and probably by herself.
