Anxiety has grown to be worse over the past 3 years. & for the past week i've had difficulty sleeping and have bad dreams every night. what can i do?

Psychotherapy: If you're not already in therapy, please consider it. It's the right way to start rather than drugs. They might be added if needed for a brief time but first try management. It teaches life lessons and it's safe. Do it ASAP since it can prevent this from becoming more 'fixed'. Don't worry - it might be a good thing in general to learn anti-anxiety skills. Best!
