I was always a brilliant student till i entered University, i felt un-challenged and didn't understood any of the course and completed my B.Sc in Mechanical Engineering degree with 2.7 GPA. Got a job of fairly good income of which i got fired just after an year, i was a very hard working employee but company was downsizing due to economic problems and bad thing happened to me, i was like a jobless engineer for an year after graduation, didn't got any job after than termination anywhere as i was not given any clearance letter or recommendation letter by the employer, one year passed as jobless person. So, than after 2 years i got admission in masters degree in Thermal Energy, degree requirements were just completion of 8 subjects, 6 core and 2 electives plus Thesis Research with Publication in Reputed Journal. I got F grade in one subject in second semester, University told me to complete requirements of degree with another subject, i picked 9th subject to fulfill the requirement, Now in the last semester when i am doing research work and applying in journals my publications, University management is saying me that i cant get degree until i clear that F grade subject for which i will be required to attend one more semester. I am feeling lost, i have good GPA of 3.5 in masters but, i am feeling like a failed person in life, i think of myself as jobless loser who attended university for post graduation and made mess of that too. I was applying for Ph.D fellowships in Scandinavian countries and now i am feeling like i am not gonna get admission anywhere as i will get my degree one year late. Please advice me what can i do, i have not told about my F grade to my family even as they feel like i am burden. I am mentally disturbed and depressed?
