Undergraduate / Unpaid Internship at an NGO; USC- Extracurricular activities or work experience [5]

You should focus on your strengths and what you accomplished more, don't draw so much attention to the issues you faced (cuz honestly they are kinda common).

Undergraduate / My Grandfather's Story- JHU Summer Internship Program [2]

I think you have a too much going on. Within the 1st paragraph we learn about your grandfather, then his view on FDR's speech, then more stuff about FDR, then back to your grandfather. My opinion is you should cut all the FDR stuff. Find a story, an example from your grandfathers life and his battle with alzheimer's. Then weave in all the other facts of your life and credentials into one grand tale.
