I took them after the death of my newborn baby and they left me feeling like a zomblie. I had no lows...no highs. Just didn't really care about anything.
Many of my family and friends take medication for both bi polar and depression and they are still suffering. They don't work for long and don't do a lot of good. Many anti depressants also interfere with sexual function, if that is important to you.
I find that a healty lifestyle helps with mild to moderate depression. Take Omega 3's and get enough Vitamin D. Those two supplements help me tremendously as I still suffer from mild depression at times. Get out, have fun and excersize. Surround yourself with positive people who make you happy. Most importantly, see what can be done to fix your marriage.
