If you keep taking those pills it may not kill you but it will damage your liver or kidneys and then you'll see how miserable you life really can be.
Lord if this request is for real then have your perfect will be done in this person's life and their situation. May they come to really know and love you and understand that You don't hate anyone, you hate sin but not us. Help them to feel your love for them as you take away all depression and anger they may have. Replace all that anger and depression with your peace, joy, and love. I pray this in the mighty name of Jesus Christ amen.
