St. John's Wort is good, but not for a long time...you can get used to it, not feel the benefit anymore. Temporarily, great.
Making sure your sleep is good is vital. Go over your going to sleep routine, make sure you don't eat 3 hours before bedtime, don't drink coffee at all, black tea only when you wake up and a few hours on. Don't drink water before sleep. Let yourself wind down, if you don't fall asleep immediately, well no big problem you're in bed resting. Take a cup of calming herbal tea with you to bed, read a little, be cosy. Put a few drops of diluted lavender essential oil on your wrist.
There is actually quite a lot of recent research regarding the effects of antidepressants compared to the effect of walking for 30 minutes every day. Walking has the same if not better results after a few weeks, but in the long run and studying relapses of depression, walking seems to be a better treatment. The problem is that doctors find it hard to prescribe walking, as the patients doesn't take this seriously and may also feel as if they haven't been heard. Walking has next to no bad side effects, antidepressants do - they mess up our whole system.
This kind of thinking helped me, now a few years back. I moved to the country, started allowing myself to take it easy. Sat down and wrote through all my routines, how I ate, how I cooked, how I went to bed...and noticed how I allowed myself to act totally against what I found nice. I like walking...but never did, I like good home cooked food, but never cooked. I like being cosy, but never gave myself the time...always stressed about something or letting my head buzz with 1000 half thought thoughts getting no order in anything.
So forcefully, 'cause I was still depressed and about as easily motivated as a sleeping politician, I got myself to get up a little earlier in the morning to enjoy the scents of the morning...grumpily with a cup of tea...but this was nice and now it's a routine, but still as nice. Then I make sure I cook 3-4 times a week, but more than the meal for the evening, so now I can eat home cooked food every day, and it isn't a major time loss. I go for walks, I get cosy in the evenings...one needs to wind down, summarise the day anyway. Doesn't take long, 5-10 minutes.
All of these little changes were quite hard to get in place, but they have really been a major change in my quality of life. And I like them, so it's strange it was so difficult to make them, but changing habits is hard. Remembering values, and giving them priority is hard too, we tend to just brush ourselves under the carpet...but what's the point of lying there amongst all the dust?
I hope this can help you a little and hope you're feeling better soon.
