weary

Grief is some of the most difficult work I have ever done.

Grief has made me weary.

weary:

physically or mentally exhausted by hard work, 

exertion, strain, etc.; 

fatigued; 

tired

Tonight I am thankful for Jesus' invitation:

 “Come to Me, 

all who are weary and heavy-laden, 

and I will give you rest."

Matthew 11:28
