Hi Debz remember that you are not alone and that you will get better.
For today, try to maintain social contacts, eat well, exercise, but don't beat yourself up if it's too hard.
Try to keep in mind that depression is commoner than you may think and that lots people who have suffered have recovered.
The modern range of drugs will almost certainly help and I would look at a getting Cognitive Behavioural Therapy which is the most effective for the largest number of people. If you're in the UK, you can get CBT through your doctor but you may have to wait several months, so if you can afford and you think it's for you go private.

Good luck
