Feeling unaccomplished =(

Lately I've been feeling down..and very sensitive, and I think it's because I feel unaccomplished..I'm 26 years old, I do go to school, currently working towards a nursing degree, but I have never done anything...I didn't graduate from HS, I got my GED, I haven't gotten my associates yet, I haven't had a baby yet..haven't gotten married yet. .just feel like I ha e made no milestones in my life...sort of feel like a waste...ughh idk..just feeling down I suppose..
