Okay here are some useful sites:
www.studentdepression.org lots of info on treatment options for depression, plus good book list for CBT workbooks. Overcoming Low Self-Esteem is good, ditto the Beck Diet Solution book by Judith Beck for dieters. I've heard a lot of praise for "The Feeling Good Handbook" by David Burns for treating depression, also "Mind over Mood"-forget the author. I haven't tried the last two books but suffice to say, there are a lot of useful books on the subject.
living life to the full-its a NHS CBT course, just google it
Centre for Clinical Interventions (CCI) - Psychotherapy, Research, Training (free CBT courses)
the "Overcoming" book series is pretty good for a host of issues such as self-esteem, depression etc. I'm not knocking self-help books but for something like depression, get a book written by an actual psychologist or expert in that field as they will know what they're talking about much more and will reference case studies. A lot of self-help books just say "think positive thoughts" or some other new age mumbo jumbo and whilst thats very nice, it doesn't help the depressed person.
exercise is good-start walking fatmanslimming. bring some music with you to make the time pass quicker. the walk will get you out of the house and the fresh air will make you feel better.
I totally revamped my diet. I now drink 3 litres of water per day. Just get a few 1 litre volvic bottles and keep filling it up during the day. It is tough to do at the start but your body will get used to the water and actually crave the water then. My skin is a lot better now too! Stick with a low GI diet-theres a GI thread on here. So basically no white bread or pasta-swap it for wholegrain/brown. Fruit, veg, fish, low fat dairy and lean meat are okay too. Sugar is out with depression. Ditto alcohol and caffeine.
I do some yoga poses and mindfulness exercises and they help me out-I would try describing them but you're really better going to a few classes to learn the poses and breathing first.
Also be as proactive as you possibly can be. I don't have a magic wand but this is what has helped me so it will work for you too fatmanslimming.
oh boggins, well done on your weight loss hun!

is the c25k training programme 4 days a week? I'm on week 2 and that's what I've been doing but I'm not sure! I'm doing the one on the NHS website where they say run on alternate days. Thanks in advance x
