Am I a Quitter?

Somehow I felt like I'm a quitter. 

Couldn't work for a proper one year already quit the job that I'm working now. Only working for three months. This month will be the last month. 

Recently I'm having some conflict between parents and boss. Standing in between both of them is really hard. The stress has been really terrible so I wrote on fb about it because I didn't know what's the best way to do. My boss saw my post on fb and yesterday she told me that she thinks I should focus on my studies first. So best if I don't work. Therefore, this month will be my last month. 

I felt bad. My actions make me felt like someone that I know. Quitting everything last minute. I do owe them lots of stuff because I trouble them so many times. Making a decision was hard. Although I didn't fail any of my subjects but it was still an unforgivable thing for not getting a 3.0 for my GPA. Won't and will not give myself any excuses. 

But I seriously felt like I'm a quitter. for not completing my task properly. :( Sucks shit.
