Hi p1994, really well done on talking to the staff member at school!!! I know it often isn't easy opening up to someone about things like that. So good on you!!
And it shows that the staff member is really taking you and your feelings seriously, it does sound like they really want to help.
Sometimes it can be really helpful talking to a psychologist/professional in order to actually avoid going back in to hospital. They can sometimes help you in finding triggers and building more coping strategies so as you're not on the road to hospitalization. So it's worth thinking about.
But if you feel fairly comfortable/more comfortable talking to your teacher, then that's a good thing too, if they can help. Remember they may not have the training or insight to help you as much though even if they really want to, so someone more "specialized" in what you're going through might be really helpful too. But it's a good start so maybe try to talk to your teacher a bit more and see how it goes.
And remember if you want to vent, talk.......whatever......we're here too!!
