First of all that's not true,
and stating this nonsense as if it were fact is to condemn innocent sufferers (mentally at least) to a life of believing they live in a kind of prison they can't get out of. Suicide is a big enough problem in this species. Suicide is higher in men, and highest in the Armed Forces.
There are many cases where the sufferers mature or develop out of their conditions.
Even in Autism, they say as you get older, you get less autistic.
Don't blindly believe every false thought that pops in front of your mind's eye.
This is dangerous (especially for other people).
I think most people here don't even know what their Mind is.
Let alone explored it. Self inquiry and meditation have transformed many, centuries back even.
Put a more critical eye on the thoughts you wish to express.
In my experience, most human thoughts that occur are not true.
This is part of the sad human ape condition we all live in and have to deal with.
