Citalopram and similar SSRI's do indeed help people recover from depression. I'd been ill for 15 years and nothing helped, yet within 6 months of being on these I recovered.
St John's Wort is not the same and nowhere near as effective and must never be taken with any SSRI. If anything, I'd recommend 5-HTP though, which again can't be taken with an SSRI.
SSRI's works by hanging onto your serotonin, the feel good hormone, before its reabsorbed into the brain, lifting the mood, making you calmer .... and your body has to adjust to these meds, hence the side effects. People often get caught in a cycle of depression - anxiety - fear - thoughts ... all feeding off each other. SSRI's help to break that cycle - lift the depression, ease the anxiety- all of which takes the fear from it, putting thoughts get out back into perspective and allowing the body to heal.. It takes months and months, sometimes a year for this to happen, but they do work. Many people of this site have recovered on them.
My son had a terrible melt down 2 years ago and was put into these meds. He went through absolute hell and couldn't work for months. Slowly he recovered after 9 months and is today well and happy again.
Yes these meds are tough, but easing onto them is the way, plus withdrawing from them over months too. You can't just stop them or the body will violently react. It's trial and error finding ones that suit you. It's not like taking an aspirin and tomorrow you'll be better. For me, I'd rather get through the side effects than have to lose years of life again, as my illness was no different from the nasty side effects.
Recovery often ten comes in waves too. You start getting better only to find yourself ill again - this is normal and seems the way the meds work. Eventually the blips get less over time and recovery creeps up slowly.
There's exciting research happening now, whereby a simple blood test will be able to determine which SSRI meds will suit you without the need for the long drawn out trial as is now.
Lots of patience, determination and understanding of these meds is needed when taking them. There are many people here who've recovered on them - in fact when recovered, they stop posting. Probably why people don't hear of them.
