The person who I know suffering gender dysphoria has been pursuing medical assistance in dying in Canada. She has been seeking it by going to Doctors for multiple years and with a psychiatrist following her.
She is a rational person who approaches it as any other chronic illness with tremendous pain. She deeply expresses how the majority of her life was stolen from her because of the illness and not being able to obtain treatment young for it because of parental figures & bad doctors.
She believes she is valid in getting the procedure to end her life compared to anyone else. Doctors will tell her she has valid points but will refuse to say much and skirt her out of their offices whenever they have a chance. She is not irrational.
I know for a fact the belief of everyone should continue living because the "what if game of it may get better" is irrational. She has had her life stolen from her and continues to live in pain but for the chance to have some humanity given to her (a safe way to die). She usually doesn't eat anything to divert her conscious to starving and where she will not focus on much. I'm a co-worker/friend of hers.
