While you’re at it Tea…you may also want to suggest alternatives to pharmaceutical drugs. Of course that depends on how receptive your friend is to these remedies. There are some herbs/vitamin supplements that are excellent for alleviating mild to moderate depression. Here’s a link with posts from me and a few others on this subject…not all of it applies to your friend but you may find some useful information. Just happens to be in one of Bosshank’s threads. 
Best of luck supporting your friend and helping her find something that will truly work for her. I gently suggest that if she needs a little more help than she’s been getting from conventional anti-depressants and is interested in a way that’s more acceptable/natural…that she find a good nutritionist to head her on the right track.
