My sister-in-law has been battling depression for two years. She's been on so many different meds, therapy, etc and nothing seems to work. She has threated suicide many times. She'll stop her meds when she thinks she's getting better, then has a relapse. She'll come around and be all moppy but then get on the phone to a freind or her sister and she acts just fine. Just like switching a switch. My brother says she has clinical depression but I think it's more than that since her moods swing like that. She'll get off the phone and act moppy again. My brother is about ready to crack too from the stress. She's had her job threatened and they said they won't tolerate this another year. What else can someone do?
