How do you manage training with high life stress?

I have been extremely stressed in my personal life. Currently going to the gym for about 60-90 minutes every day 6x a week. . How do you manage training when dealing with very high life stress? I lost my dad to cancer and my body is having a hard time performing. This is not about not “making time.”

Edit: Thank you to all who gave me kind words and advice. I am scaling back and letting my body just breathe for a bit. I’m really too upset to focus on much. I will be sure to life but grief is a bitch. To those who have lost a loved one too, thank you for kind words. Hope you all are well.
