Hi, appreciate your time
I'd be really grateful if you can help with my scenario below

I am currently a year 3 (out of 5) degree apprentice, working for a start up engineering company, in an intense busy role. I’m 21.
Over the last few years or so, I've started a business, which I am now realising I want to be my primary focus, and have lost interest in continuing my engineering degree and role. I still have a passion for the subject, and may return in a few years, but as of now, engineering and university does not contribute anything towards what I'd like to achieve in 4-5 years time, so I don't see the point in doing it.
At the minute, my daily routine is up at 7am, get to the office and arrive home for about 6.30pm. Sometimes I have the burden of doing university work during intense term times and this then puts me on 15+ hour days doing work and university, both of which don’t even contribute to what I want! Add the business into the mix, and a few other personal matters, and I’ve found myself working ludicrous hours over the last 2 years or so but for what benefit!- and voila - burnout.
I’m 21, I can afford the risk of leaving my job and uni, and getting another job to pay for my life in the mean time which is less hours and closer to home/ work from home, I’m just trying to find another role which is more suitable, but just need to hang in there with this one until something else lands. —— My Problem is:
University is now reaching the final stages of the academic year, and I really have no motivation to continue, I don’t want to spend 10+ unproductive days staring at my laptop screen not being able to get anything done and the scroll of other things that come with it. I’m very stuck now, I have a looming deadline in 3 days which I’ve only done 15% of, my mental health is really bad, I’m starting to get really really bad addictions and my physical health is in poor state, currently have an eye infection and a few other rolling issues. Still have 2 months left, 4-5 assignments to hand in including the one this week, and 3 in-person exams to sit.
Have tried taking breaks, and doing things I enjoy, but unfortunately, the reality sits where it is, and when I get back into work the intense workload, and university deadlines are still there, with no progress made. I’m now revolting doing business work, and my business progress is slowing down to an intense workload, and a burned out person stood at the front of it. I don’t mean to be very complaint-full or negative, sorry if it comes across that way, just want to be brutally honest, and take opinion.
Not really sure what I want from posting this, any help much appreciated community!
