I've felt like you too. My body depressed and my mind kind of numb. Try reading an uplifting book or watching a funny movie. WE have a channel here in South Africa that occassionally shows clips of really serene settings, especially in the morning. I find this very relaxing and motivating.

Alternatively, do you have a pet? I find if you realise you are responsibly for that animal; it's companion, feeder... it uplifts you as you realise you are needed and have a purpose.
I've never SI'd, but OD once. I had genuine intentions and spent a few days in hospital. Yesterday I started getting strong suicidal thoughts. But i'm an intelligent person, I have a good life-style, I have a family, a few friends... and I cannot let myself get involved in something like that rationally.

seeing my p-doc in 1.5 hours and need to discuss this with her - in future I believe the responsible thing would be to admit myself to hospital.

BNLsMOM - please look after yourself, post here if you can, and really consider everyone around you as well as yourself. It is very responsible of you if you admit yourself to hospital if you really feel the images getting too bad.
