I really need to work on this guilt complex thing

I dropped my History class today. Between being sick this week making me fall really far behind and the stress caused by getting used to my meds, a job, an internship, two labs, and two clubs, something had to go.

Job can't go because of bills, internship can't go because I need it for my major. The clubs can't go because I live in one and would be lynched if I quit the other, and my meds certainly can't go, because it's not like I could handle myself BEFOREHAND.

So the elective went.

But the professor? She's so nice, and so understanding, and so friendly. I don't feel like I dropped her class, per se. I feel like we've broken up. "It's not you, it's me."

So now here I am, running around, and feeling like a terrible person.

Will someone please explain myself to me? XD
