We humans need to reboot and learn to have gratitude for our doctors, police officers, or those providing essential services, otherwise they would feel that it's a thankless job. They risk their lives for others and don't even get time for their own family. We need to be more compassionate, caring towards them instead of misbehaving.
Becoming the character you are playing might work for some, but for me, it doesn't. I always maintain a gap between myself and my character because if I will go so deep into it, it will get difficult for me to come back. You should work towards understanding the psyche of your character and then play it.
