Also, just a quick thought. If you were on the pills for only four months and you already started to feel really down again, you may not be on a pill that is right for you. You could be bipolar in which case pills for depression can actually worsen your condition. In this case you need to be on a pill for this specific condition. Or if it is in fact just depression, maybe your body does not handle the pills you are on right. The answer is not always more meds!
As for going off of meds "for a while" this is not recommended. Yes, it is definately worth trying all of the natural remedies as they may help you greatly, but for a lot of people, medication is necessary ( at least for certain periods of time). A lot of people make their condition worse each time they decide to stop taking meds. You may feel wonderful for about six months or so and then have a relapse that is 100 times worse than the last. That is what always happens to me anyway.
But anyway, in the future if you do decide to go off of meds for whatever reason, just make sure that you talk to your doctor and get the "correct" way to stop taking your meds. You cannot just stop taking most depression pills as it will give you horrible side effects and possibly a nervous breakdown.
This is an old post, so I do not even know if you are still reading this, but I hope you are feeling better!
