Daniel,
I've been taking St. John's Wort for a few years now. Whether or not it is helping me is really hard to say. I also take fish oil and a multivitamin. I do remember that one of the contraindications of SJW is stomach trouble (and sensitivity to light). Both of those problems went away with me and now I'm fine. With everything else going on-your eating habits, for instance-it's impossible to say if this is the case with you, just something to be aware of.

Also-and this from the link below:
"St. John's wort interacts with certain drugs, and these interactions can limit the effectiveness of some prescription medicines."

I would not write off anti-depressants and honestly it sounds as if you could benefit from one. I tried a handful and they were briefly very successful (at creating euphoria) but then ceased working. I know you have a better health care system across the pond (unless they've gutted it in the interim), why not take advantage of it and try and meet with a psychiatrist and at least talk about some medical options. You sound as if you are really struggling. You know, working in a job you detest and being away from a sweetheart can make the most serene of us ugly. Just keep your eye on the ball and try your damnedest to focus on being together and ultimately finding that job you desire.

My fiancee is millions of miles away at the moment so I know what that's like. But she's worth the wait and I figure it's a small price to pay in the grand scheme of things. Be well.
