I was afraid to go to the school therapist.

I eventually went.
My advice to you, is that going to them can't hurt you in the way you're afraid of. You don't need to know what to say. It's their job to help you - they'll help you know what to say. Even saying I've been having a rough time and I don't know what to do gives them alot to work with. Even just showing up does too.
Don't expect going to make everything magically better because it won't. For me, I waited till the last moment to go. I wish I had gone sooner. By the time I got there, I really was in crisis. They could have done so much more if I had gone sooner.

PLEASE try going, it could help and all it can do is use up maybe and hour of your time. You never know, it could help.

Also, keep in mind that school therapists have their uses, but dont be upset if they don't do what you need. Keep in mind that going to a therapist not school related might be more beneficial IN THE LONG RUN.

But please, for now, try it?
I wish I had earlier - I know you don't know me, but I have been in your shoes, and if I were able to give myself advice when I was at where i think you are now, I would tell myself the same.

loads of hugs
and hope all goes well with you
