Mark’s college funds

Welcome everyone! My name is Mark Miklos and I'm from Hungary. I'm 22 years old and I study geography (GIS) on university. I have a 5 years old brother and a 16 years old sister. When I started the university, everything was all right, but later everything became worse and worse. At the start I had really good marks everything was going smooth. Later on I started to work also next to my studies because I didn't want to "just live on" my parents money. They always help me in everything and support me as much as they could but I always felt like that I have my brother and my sister whom can't work of course due to their ages and they need the support not me.  There was an accident in my family when my grandfather passed away then I felt completely broken, I failed lots of my exams, I couldn't handle the pressure at the places where we've been sent to work and the pressure of studying at the same time. So my marks just got worse and worse and now I have to pay for the semesters. Also I was selling PC games on e-bay and I've got scammed there and my account is in negative balance for 150 euros. There are companies whose offer job for students, you work full time, for a really bad payment (my highest was 200 euros for a month!) and you're treated like prisoners at some places, so I just quit the job. Though if i wouldn't work for example I couldn't buy any present for my little brother, for my family or my girlfriend. I can now focus on studying and my marks are actually good now. I really want finish my studies and I to make my parents proud of me. Every little help would be greatly appreciated! Happy new year for everyone and have a great day! Greetings: Mark
