>gone through the same conditions without having the crazy thoughts

Not a psychologist either but from my anxiety experiences and what I've researched I've found that everyone gets crazy thoughts but people with anxiety conditions start to worry that their thoughts are wrong and no on else deals with them. My anxiety dwindled when I realized they're just thoughts and the crazy ones cause anxiety because my brain is trying to "protect" me.

So, people that don't have issues are really just able to dismiss the thoughts because they know they're only thoughts and nothing else.
