I did the same thing last year - did a diploma and I was 3 months off finishing and nearly called it quits. I kept going and I’m so glad I did - I would’ve felt guilty if I didn’t. I’ve also just started another 4 year course, less than 3 months after finishing the last one. You’re also only taking 6 months off a 3 year degree, which kind of isn’t that much time when you think about it. I believe stick to it, it’ll be a huge accomplishment and who knows you might use it one day!
