I got a C+ in Pharmacology & I am really discouraged about my future as a nurse ..

I’m a nursing student in NYC . I graduate in May 2018 . My spring semester of 2017 was so difficult for me . I struggled through it .. I was taking pharm , peds , maternity & psych all in one semester. With all the studying I had to do .. I couldn’t manage to memorize all of the drugs ! It was impossible. My first 2 pharm tests , I did great on .. but the last 2 .. I got 70s .. resulting in my C+ . In all my other classes, I got As & Bs in .. but this C+ is killing me .. its my first & only C grade ever . I feel as if when I graduate .. I won’t get into a residency program because of it .. I won’t be able to do my masters .. I wont be able to get a job .. I’m just really discouraged & scared . Nowadays, it seems as if passing the NCLEX isnt enough anymore & here I am with an ugly C+ .. does anyone have some uplifting words ? Its not even 2018 yet & I’m already sad about being unfavorable even more because of my C+ on top of being a new grad with no experience that no one wants to hire .
