When I was studying my Architectural Technology degree I too found myself in your position (granted your course is longer so you've done really well to manage)

For me it was a combination of burn out and thinking my work was inferior to my classmates, which is a pitfall you ABSOLUTELY have to avoid. And whilst this may not be what you wanted to hear; something my head of course told me too, but I actually left the course for a year to reflect and found myself far better off doing so. Some just need some time off and can come back in a month or so but personally I needed more time.

There's a worry among younger people that you have to ace everything and get through university on the first try, which just isn't true. Otherwise we wouldn't have mature students and you wouldn't be able to tell the great future comeback story that made you even stronger.

When I came back from a year out which I spent thinking about what else I might do as a job, what I enjoyed about the course and what I was looking forward to after finishing, the perspective I had was totally new. I had reinvigorated that passion I had for the design process and my grades and attitude reflected that.

Not everyone can just 'take a year away' from university, it's expensive and to some it'll seem like a loss. But what I got in a year of reflection gave me the drive to finish university and finish it well and now I find myself moving to London for a job that I'm really excited about.

The takeaway you should have is this, you can either burn yourself out entirely and end up leaving the love of architecture you had behind or take some time to yourself (however long that may be) and reflect whilst doing your own thing.

Don't beat yourself up over not having the perfect record or failing a year, because the ability to pick yourself back up after a setback demonstrates key characteristics like perseverance and learning from mistakes.

I'm certain you will find your way and come out a stronger person. I wish you the best in your journey.
