Hi Grapes,

The first thing I would suggest is to get yourself carefully tested for the many common purely medical/nutritional issues that can contribute a lot to depression. There's a list here:

For instance, if you have hypothyroidism or a vitamin deficiency or omega 3 fat deficiency, or gut problems or heavy metal toxicity, the first way this might affect you in any way you notice is via depression. These are common problems and are not always checked by MDs.

About changing your thought processes, you might find these notes to be helpful:
