What should I do? I hate how miserable I am?
What is it that makes you miserable?
I'm not really sure. I just feel miserable all the time.
I'm sorry to hear that. Feeling miserable all the time is bad, and can affect your health. You should talk to someone like a counselor to see what can be fixed.
I don't want to talk to anyone about this, it's my problem to bear and nobody else's.
Everyone has bad days but to consistently feel miserable all of the time is unhealthy. It would be great for you to talk to a therapist about how you feel. This will help you to understand why you are feeling the way that you are.
