No, Khandro, there was no alternative. I had been diagnosed as clinically depressed and had done the talking therapies, the counselling, the meditation. I hope my wife wouldn't have left me if I didn't get better but the strain was very real. I hope I wouldn't have committed suicide, but there were very dark times.
Thankfully I improved after taking the medication for a while (the first type didn't suit but the second lot did) and stayed on the meds for probably two years. Hopefully I never get that ill again, no idea what 'triggered' it so of course don't know how to avoid it.
I know the signs, though, as does my wife, so if it does recur I'll be banging on the doctor's door begging for help.
I am sorry for your loss, and hope you and your family are able to find some peace and comfort.
