I guess my first question would be, is there any chance of you seeing the psychologist more often? Or even be able to chat to her on the phone or via email for more support?
There is a website called MoodGym http://moodgym.anu.edu.au/default.asp which provides CBT online to help treat depression, which might be worth you having a look at.
Just a question, please don't take offence, but do you think it is wise to be looking after small children? I understand how they would distract you from your issues, but that really just puts off the inevitable. Also, if you are feeling depressed, the added stress of looking after littlies may not be in your best interests. Is there something else you could do to keep busy?
I'm sorry that your local doc is not supportive and yells at you, maybe you could take hubby along to your appts so the doc is less likely to be so aggressive?
about the journal, I've filled several in my time lol, can you get a locked cupboard, or a locking diary or similar, I understand about nosey teenagers, they can be so inconsiderate, but you are entitled to your own piece of privacy if you choose to write. I have a locking desk cupboard that I have the key to, hidden in my purse.
I hope these suggestions are of some use Jane.
