If you suffer from severe anxiety you can apply for disability through the social security administration. Your physician can help you with the paperwork, however, it does take time.
You can get social security disability or SSI for anxiety problems, but they must prevent you from working, and you must have evidence of treatment for these issues.
If it is work related you can go on leave and they will pay you. If it's not related to work you still can take leave but they may not pay you for your time. Either way you need a doctors note.
