I too am 24 and in college not so near the end about 2 more semesters left but in november my dad passed away at 74. Definetly one of the most difficult things I have ever gone through. to tell you the truth I told all my teachers what was going on and did as much or little as possible I mean hell this is a major life changing event. School just had to go on the back burner. I realized that I had to take care of myself first. School will be there but it is important to take care of you first. that was my attitude and it took a lot of pressure off. I even considered taking incompletes but my teachers were most understanding and gave me better grades than I deserved for the work I did. you are going through a vey difficlut thing. Give yourself credit love and space and don't worry about school so much.
hope this was helpful YOU are not Alone.
