Anxiety is about fear. To cope with anxiety you learn about yourself and your fears with a psychotherapist.

Marijuana is a way to avoid learning about the fears that create the anxiety in you. It's avoidance which is a way of coping but not a way of healing. Marijuana can induce paranoia and as MissC said above, schizophrenia.

There are other ways to feel better. Psychotherapy is so helpful. In addition to psychotherapy, there are other things people do to feel better such as relaxation techniques and meditation.

Of course you want to feel better. Feeling anxious doesn't feel good. I hope you'll choose a healthy way to feel better that will help you all your life.
