I think I need to see a therapist.
What is your reason for feeling the need to see a therapist?
I just feel like I need someone who is mature that I can talk to and express myself.
It's admirable to ask for help when you need it.  Reaching out to others when you feel lonely can be a source of comfort, and can also help with deeper issues.
This saying isn't exactly true. We were created to use our own strengths when we are on a journey.
Well either way, reaching out for help is the first step when you are in need. It is great that you took this step towards clearing your head and living a more happy life!
