You are overwhelmed, I believe. I advise you to go part-time also and try to do as well as possible. I can't imagine how it is to go full-time and also work because I never worked during college. Some students don't work and just focus on academics. I did well in college but it is nothing to brag about because I never worked while in college. My point is you seem capable of doing college but have too many responsibilities and are overwhelmed. Although going part-time may take more time, if you do well academically, this will boost your confidence and help motivate you to continue. Best wishes!!
