This is why this site exists and you are free to discuss your thoughts with others here .
There is still a stigma attached to suicide even in today's world of acceptance which in my opinion is morally wrong . If you discuss your thoughts it has to be with someone who you can confide in , a good friend who will not betray you otherwise authorities may be called and you don't want that .
In an ideal world you should be able to freely discuss your intent without resorting to therapists.
When someone is in a lot of pain and there's no hope of recovery then those around them kind of understand why they want to escape the pain .
Suicide is still a taboo subject and I don't ever see that changing any time in the future unfortunately. I agree with you that you should be able to freely discuss your intent without prejudice, for the most part people don't know how to react or if they do it's almost negatively and then distance themselves from you . Not a good situation to be in when you open up your heart to someone only to be let down by them .
It's good that you found this site , amazing people here who will interact with you . Look forward to your posts
