ok, im not sure because im in australia, in australia they only tell your parents if your under 16 i believe. You dont have to talk to a man, but it may not be as bad as you think!
They should not tell you that your overreacting or think less of you for being a teenager.
If they do they are incompetant And you can find another.
Can you ask your gp or ring up a community or youth centre in your area, they can give you these answers without actually starting any process.
