Fluffanstuff - I would also recommend joining the low carb Bootcamp (well I would, wouldn't I, seeing as wot I started it! 
). But reading your posts it struck me how well it could suit you, and how it might address some of the issues you seem to have:
"I have training in nutrition and diet so I know whats good and whats not"
IMVHO and E, this means you are likely to have been taught that carbs are good and fat is bad. (Forgive me if this is not the case when it comes to you!).
"many of the mums go to the local weight loss clubs w.w. etc. and I wouldnt feel happy mixing my personal and work life in that area."
What about your local gym/leisure centre/pool - they can't all be there all the time! To be honest, this sounds like a bit of an excuse. And I can assure you that all that people would think if they see you at the gym/leisure centre/pool is that you're putting into practice what you're telling them!
"I eat healthily and am on my feet most of the day. I have really bad anemia and sometimes I can resort to a small chocolate bar and a glass of coke just to get me through the last hour of work. In my job I can't eat little and often."
I appreciate you have anaemia. But how is eating chocolate and drinking Coke part of a healthy diet?! All that sugar will see your blood sugar levels spiking and then dropping very swiftly - leading you to feel worse, and making you feel hungry. And eating little and often isn't necessarily all that good for you - constant little spikes of blood sugar and therefore insulin, and therefore fat. If you can, eating 3 meals a day without snacking may be better for your weight in the longer term.
"I also have loads of case work to take home which effects what excersize I can do in the evenings"
I sympathise. But is this every evening? All evening? You couldn't even fit in a half an hour walk? What would you advise your own patients here?
"I had chronic fatigue a few years ago and lost 3 stone within 2 weeks I was THAT ill. Food = energy and in order to just survive a day through week my food intake did go up. Now a couple of years on its levelled out and I wouldn't say my intake or portions are large ? How can I loose weight im getting so demotivated ...scuse spelling so tired !"
You need to be eating food that will keep your blood sugar levels stable, so that you get through the day feeling energised. Of course food is energy, but you need to be getting the right energy, not just eating sugary snacks/drinks, so that you are getting the most out of what you're eating without putting on weight.
"I think the low carb might work I get really bad headaches and feel a bit depressed when I come of them though , I don't eat carbs after 6 and I dont like bread or pasta anyway so not really a carb fiend , just if I cut them out completely I get a stonking headache."
Low carbing isn't about cutting out carbs completely. You are encouraged to eat your carbs in the form of vegetables and salad. It's about re-balancing your diet and the proportions, so you're switching from carbs:protein:fat to fat:protein:carbs. What you have experienced with your headaches is carb withdrawal, which is common in the first few days, but should pass once your body is used to it. It suggests, though, that you're eating a lot of carbs normally, if you react like this when you cut them out.
"I don''t know wether im just not healthy enough to 'diet' but im sure if I lost weight it would help with my energy levels so its a real toss up."
IMVHO, eating low carb is a much healthier way of eating, which has weight loss as an additional benefit. I suspect most people on the Bootcamp threads would confess to having a much better diet now they are low carbing than before! I can't see how your health issues would stop you losing weight.
"I think im going to go to my GP, and see if there's a solution there, just kind of had enough now."
You sound really fed up, and my comments are meant to be helpful and encouraging. I hope that your GP can help you, but I suspect he/she will not recommend low carbing as it's something that few doctors know that much about. I was very interested in cathyandclaire's own admission here!
If you want to know more about low carbing and how it can help deal with all manner of health issues, least of which is weight loss, get hold of a copy of "Escape the Diet Trap" by Dr John Briffa. It is a complete revelation! His blog is worth reading as well
