prayers for my friend Joel

My friend joel really needs prayer. He is a brother in the Lord, but is very much stressed and worn out working a lot, sometimes getting less than 2 hours a sleeps, he works 7 days a week an really is getting worn. At the same time he is always helping others and reads the scriptures everyday and going to bible studies on friday. He is hoping he could go back to school for music to be a music teacher and get his license for it, he already actually teaches music, but works overnight at a truckstop where the stress by management really gets to him, they want everything perfect and everything. Plea lift him up in prayer also his friend Josh who is working a lot to trying support a family.
