Just need a little encouragment!

Hey guys! I know this is silly but I just need some encouragement!! I'm worn out. I'm a full time student and I work full time and I have a 4 month old baby. I literally get maybe 4 hours of sleep a night because my baby will only sleep if he's with me and he's a very restless sleeper! I have so much homework due and I'm just exhausted. I only have two semesters left of school, but I honestly don't know if I can do it. It's just so much. Not to mention I still have laundry and dinners and regular cleaning and household chores to do. I'm just so overwhelmed!

Just to add, I do have a wonderful fiancé and he helps as much as possible, but he works 12 hours a day and doesn't get much time home!
