Mephistopheles;4675090It doesn't sound to me like you were just "lazy". Not being motivated to do anything constructive can have many causes.
Actually, at one point in my life, I wanted to be a plain lighthouse keeper. Fortunately, these jobs are VERY rare now.
Many of us have had one or more depressive episodes in their lives. Try to get some professional help to defeat your demons before it is too late.
You managed to study at a university. Do you really want to do a fucking miserable low-paid job for the rest of your life thinking about what you could have achieved if you had decided to stand up again?
Agreed. I know someone who got kicked out of uni (for failing end of years exams IIRC). He's now looking at doing an Open University course, as the year he did counts as credits towards that. You get to work at your own pace as well.
What course are you on? If you're still interested, then a job in that sort of area would be good to keep enthusiasm up.
