Call a trustworthy person, be it a friend or a work colleague if not your family and with them quickly GO to an EMERGENCY ROOM/casualty of a nearby hospital after which a PSYCHIATRIST will be called to attend to your concerns on an URGENT basis, bypassing appointment system of OPD.
Once you are examined you'll be provided the treatment you need and it will reduce your negative thoughts. The Psychiatrist will then call your parents and inform them, educate them about your issues so that they can be your support in the recovery process
Next Steps
Go to a Psychiatrist immediately. Keep talking to your friend/family about this.
Health Tips
Don't stay alone. Keep your emergency contacts handy.
