When it works you'll know. You'll feel better and probably get some side effects. Don't worry what others think, but it's not true that Indians or African Americans didn't deal with these problems, they just historically used their own medicine, herbal medicine and shamans. It's still medicine. Do what works for you.
i'm on prozac too, 60mg. it might take up to 2 months to fully work but ask your doctor to see if you need a change. i know about people not understanding that you need medicine, my husband is one. he's only mildly supportive, you need to find family and friends who are supportive as well as maybe a therapist. they can help too. just don't let people get to you and know you are doing what is best for you with the help of your doctor. just keep in contact with your doctor about your meds and think about therapy. when i've been off my prozac before and go back on it, i feel the effects in a matter of days but everyone is different so just ask your doctor if you gave it enough time to work, you may need something else or a dose adjustment. hang in there and find support here and with as many people as you can, it does help.
