Stressed , depressedand anxious

Plzzzz someone give me advice

I failed in my first year engineering . I am a only girl in my class who fail in first year engineering. I had 7 backlogs in which 4 exams I have given recently. Out of it I had to pass atleast two main subjects but I failed in three subjects and I got a year back now. I was prepared for the three subjects to atleast pass in that subjects. And one I was not prepared even to pass. I was staying positive for my exams but somehow I wa getting negative thoughts. I don't know how to study perfectly don't know how to manage time. I took a whole month for one subject and only half syllabus was completed by me in whole month.Now i have to study for 6 subjects within less than 2 months. All my classmates have promoted to 2nd year I am stuck in 1st year only.They are my seniors now.I am jealous of them they are doing further studies and I am free doing 1st sem.

My grades are horrible and year back student too. How will I get a placement or internship or a good job with this result. How ?

I don't know what and how to do now ???
