I think maybe the reason you are so tired is because you are being a bearer of the weight, you are doing your job! Please don't feel as though because you are the male, and you are Daddy, you have to bear all the weight. You are doing a great job, you are still standing each day. And if it gets to the point where you feel as though you can't stand each day, take a break for you. Remember to think of yourself in all this as well. My grandma keeps telling me "Your children feel how you feel." So if you need to take a break, take it. Please keep your head up, keep faithful, and stay positive. You really are doing a wonderful job.
As a girl, woman, whatever... I can honestly say that you are a father any girl could wish for, and a husband any woman could dream of. You are really in my prayers each and everyday, along with your daughter, your wife, and your son.
