I'm currently studying Physics at UCL (first year) but I've realised it really isn't for me - both the course and the uni itself - and will be dropping out by the end of first term. Along with this my mental health issues have flared up which just amplifies how bad everything is. I really don't want to wait around for ~2 years so I'm going to be applying by the January 2018 deadline for a different course (Computer Science).
I know I have to declare the fact that I dropped out on my UCAS form but should I mention it in my personal statement? I'm pretty sure I could spin it into something positive - as in "it was the computing module of my physics degree that made me realise I much preferred programming" etc, but I feel no matter what dropping out looks bad.
Also, slightly unrelated, but I dropped Computer Science after AS. Not due to a bad grade (got an A) or a lack of interest, but because the teachers were awful and there were no good resources available for it. Will this look bad on my application?
Finally, do I need to explain my plans for the next ~9 months? I could probably BS some stuff about how I'm going to work on my own projects or something but honestly I'm taking the 9 months to sort out my mental health issues and such.
Thanks in advance
