Gourmet I've used the Mood Cure, and I found it brilliant - it made a real difference in a short time: I'd love to go to the clinic itself...
mulranna I'm not preaching, and I know it's really hard, especially when you're feeling bad, but I find that food really affects my mood: things get appreciably worse for me if I'm not eating enough fresh stuff (plus I am a binge-eater at times, which is much, much easier if there's sugar and processed food about). But I do think you need to go back to your GP - you're not a "relapsing failure" - but perhaps you have "recurring depressive disorder"? Those are hefty amounts of drugs you were on before, but this time, perhaps if they start you off on a low dose of something, it will help you get better - it sounds like you were in a total crisis before, and when things are really, really bad, sometimes loads of drugs is the best way to get healed. I honestly, honestly think it's worth going to your GP - they won't even necessarily refer you back to a psych at this stage, in all honesty (unless you want them to): it sounds like your anxiety is through the roof, and if you're weepy, that's also a sign you're depressed, as you know. Preventative and timely action now might help stave off the worst - kind of like if you go to the doctor when you have a chest infection now, you won't end up in hospital with pneumonia? (Personal example: long story!)
Also, how about counselling and CBT? Especially if there is a "reason", counselling can be extremely useful, and CBT can be great for dealing with your reactions etc
You deserve to be well, and I really think you should consider at least the medical option. I completely understand about the fear of "going back" - but I think if things aren't improving, it's worth getting help now in the hope that you never end up as bad again.
