EY is killing me!

6 Months ago I moved to another city to join EY MENA for my first job as an associate. Fast forward to today, due to the immense workload, I am getting suicidal and I am unable to sleep for days and days. I reach the office at 9 am and I won’t get free until 1:00 AM sometimes even after getting off after 1:00 AM they assign me tasks that need to be done before early morning. This extreme workload and being far away from home for many months is killing me. I never felt so suicidal in my life.
