Is it okay to let you know that I've had a headache for 3 weeks now?
I hope this is a joke. Why have you had a headache for 3 weeks?
I'm just bored of it, I'm tired of worrying about school, my parents and the work that needs to be done.
If you've had a headache for 3 weeks, you should go to the doctor. You need to see if there is a medical reason for it.
I hate doctors, I just don't want to.
Doctors can help you, why are you afraid to go to one? They can give you medicine or other things to help your head pain so you can function without them holding you back.
