Hi Lizzy
Welcome to PC. I think you will find good support here. I have.

You don't say how old you are so I am assuming you're underage.

I encourage you to talk to your parents. If you are not comfortable telling them everything you could tell them that you have been having a hard time and would like to see a therapist. If they ask you for further explanation hopefully they will understand when you tell them you're not comfortable talking about it or that you don't think you can put words to your feelings.

When I have something I think I might struggle with I write it out.

If you really feel you can't do this, my next suggestion would be to talk to your school counselor or a teacher you feel you can trust. That person can hopefully help get you the help you need.

Hopefully your parents will understand and get you the help you need.
