Can't catch a break...

It seems like it's never going to end... The pain, suffering, stress, emotional turmoil... My best friend gets hospitalized and needs emergency brain surgery, he's barely recovered and we're told he'll be going in for more surgery in the summer.. My mom had a really bad fall and broke 2 toes which is going to require surgery, as well she has multiple breaks in her foot.. I had to drop a course in school because with everything happening it's become way too much for me to handle. I went from all nighters in the fall for school, barely finished exams, then spent Christmas in the hospital with my best friend either staying the night or being there till late and back early in the morning... As soon as he's back home I'm back in school trying to do 4 courses thinking it would be fine and for the first time ever I dropped a class and my mom breaks her foot and now is on bed rest needing surgery.. She's not young, we're lucky she didn't break a hip or anything... I'm just so warn down and I have exams all this upcoming week... I just want to sleep....
