Speaking as someone who has depression and who has in the past had suicidal thoughts my feelings are as follows:
Talking about if someone has suicidal thoughts doesn’t give them thoughts and is something I have been asked quite often over the last few years with the plus side being I have much less suicidal thoughts now than I did back in 2005.
As a general rule the events leading to someones depressive illness are the main cause of suicidal thoughts (least in my case as many factors in 2005 led to me attempting self harm). As the events of 2005 were the main cause of my illness that may explain why I’ve not tried killing myself lately. It doesn’t however explain why I still continuously feel tired which was the first symptom I had
Hope that helps anyway
