now here, you are presenting your frustrations rather than clinical depression... a suggestion could be to seek for career counseling which can help in career exploration based on your personality, interests, and skills...one of the popular career exploration tool is "self-directive search" (you can google it as well) which can help you assess your career path...

to summarize your diagnostic summary through treatment plan is to seek career counseling at your university career centre, career counselor, employment counselor or the local career center/ public libraries...hope this help you.
