Big hugs! I am now retired so this happened a LONG time ago. But I ended up dropping out TWICE. Once when one of my children had major surgery and again when life as a single mom without ANY support made it impossible. I later went back and completed.
If you feel that you can stick it out now by all means please try? It may actually turn out to be a great distraction. And I agree with the person who said if she wasn't able to stick it out for the short time nursing school takes then life's unexpected ups and downs would also be too much. From someone who knows very well how devastated you must feel now, there really is someone out there who will support you through the worst life has to throw at you. I had this happen for me and believe it will happen for you too.
