I'm sorry to hear about this. Depression after a stroke is very common, and it certainly does not help to have other regrettable life circumstances.
Unfortunately, there is no
magic bullet for depression. When a patient of mine is suffering from depression after a stroke, I will sometimes try an anti-depressant, but I always strongly encourage them to seek out the help of a Psychiatrist or Psychologist. They have much more experience with lifestyle modifications and medications that can help. If you are interested in trying a non-medicine centered approach, I would start with a Psychologist. Psychologists are trained in treating depression without the use of medicines. I think you might find that very helpful.
I find the main hurdle is getting people to go for their initial visit. There is still a large stigma that surrounds seeking the help of a mental health professional, but I find that once people go for their initial visit, they continue to go thereafter.
