Well it sure did just creep up on me, and very recently too. And like Raglet I have psychology qualifications etc!! Easier to help others than spot it in myself. My partner sent me to the docs as he was worried. I had really lost my temper with him when he said he thought a bit of therapy might help - I can smile about it now but I was so mad. "Therapy, me? I'm coping fine". Ha Ha, was I not.
I went to the doctor anyway to talk about the increased pain and the issue of my anxiety came up and bingo I started crying! Tissues out of desk drawer. Anyway he referred me straight away to the GP practice mental health nurse. I have, without a doubt, become very depressed because of the constant stress of managing a chronic illness, and probably because I was flaring. The nurse said people like me were the last to notice what is happening and the worst at going back to basics to sort it out. So am now resting better, doing some cognitive behavioural work on my negative thinking and waiting to see a specialist to get anti-depressant prescribed (I have multiple allergies and need specialist prescription as Prozac and the like flare my lupus). I have also rebooked onto a pain and stress management course I did 6 years ago, as I sort of lapsed from all the helpful stuff I learned on that. I know there are ways out of this but until last week I could not see them. Sometimes we need a helping hand.
I think admitting it is the first step - hard to do I know when you are feeling that mix of blue mood, and being angry and understandably frustrated. I still feel very depressed but I don't feel quite so lost now that family and medics understand what is happening.
So my advice, even though you might be embarrassed, uncertain or plain old frightened, summon up the energy to talk to someone, once you start it becomes that little bit easier.
