So I think I may have been suffering with anxiety since 2021, but 

So I have a stutter? But last year it wasn't bad but now my stuttering has gotten to the point where I can't even get words out until I stop talking and then talk again but I'll stutter again when I talk? 
But when I searched it up on why I'm stuttering it showed up brain cancer, and strokes brain, damage etc. And now I'm worried about it

And I also been getting alots of headaches aswell (they aren't bad just annoying) and I don't know if me overthinking to much did it or I'm just to stressed, about my health, and stuff
(Reminder I don't have a therapist, psychiatrist and I'm not on anything,)
I'm scared that I might have brain cancer beacuse I'm overthinking about it.
