What antidepressant are you taking? I can't take HRT so I'm on Citalopram, one of the SSRIs. They have a bad press and need lots of support from the doc, but when the side effects go, during a 4-week period, or sooner, it's good. At least it is for me. I still go up and down, but at least I can sleep.
St John's Wort can be dangerous. It can have a depressing effect. Be careful with it. If you can, go and see a registered herbalist. A good one! Herbs can be harmful if you're not careful.
There's also something else you can try. It'll be hard when you're depressed. It's a type of meditation that stimulates the vagus nerve, which is inactive when you're stressed and depressed. The nerve (or at least the massive network of verves!) is active when you're in a social and loving mood. Do the following:
Sit or lie comfortably
Take a few relaxing breaths and let your muscles relax
Think about someone you love
Think or say the following:
May x be safe
May x be happy
May x be healthy
May x live at ease
You can picture them as lightly or as deeply as you're able.
Then move onto someone else. Do about 2 or 3 people for about 5 mins each. Then say it to yourself, even if you don't feel like it.
Try smiling a little as you're saying the phrases. Your subconscious doesn't know what's real and what isn't, so if you're smiling you must be feeling better!
It will take a long time, several weeks, but each time you do it you're doing yourself good. You will have good days and bad days but just keep going. The research was in New Scientist so is trustworthy.
Avoid alcohol if you drink. It's a terrible depressant and the acetaldehyde, which is produced as a by-product of alcohol metabolism, is a poison and actually make you crave more alcohol! It's a vicious cycle. I have a hot choc drink of 100% cocoa, honey and milk,
Let us know how you get on.
Love and kisses,
