Try primary care doctor and get a referral to a psychiatrist.

Sounds silly but deep and slow breathes will help you calm down when the kettle is boiling over. Exercise helps tremendously as well!

Practice mindfulness and be honest with yourself and/or the psychiatrist about what is causing you stress (finances, job, school, etc)

Break it down and see if you can build back in a way that allows you to move forward with all goals and priorities.

Also, try CBD if possible, but its a crutch no a solution. Best of luck!
