I am currently doing my second bachelor's degree after having gotten very sick towards the end of my first and not being able to take the classes that I wanted, or the sufficient research experience for a PhD. Does this look damningly bad for graduate admissions? I am also a little bit older and my grades towards the end of my first degree aren't so great (went from a 3.95 to a 3.2). Sorry in advance if this is a silly question, but I'm pretty nervous and don't know where else to look.
There is nothing inherently problematic about getting two degrees. There is certainly nothing problematic about getting sick. You appear to have went back to school a second time so the first is only loosely relevant.
One should not be generally concerned about "extra" education when you are going for a PhD. (I have met people with multiple PhD's in different subject areas.) Perhaps if you had 3 or 4 undergraduate degrees I may wonder about the intensity of the programs or if you were better served by outside activities/internships - but this can all be explained with a good letter.
