All the difficult bits then!
I can absolutely see why you need to consider changing school, but equally you'd only be starting ATPL groundschool in September as you won't have the hours to do the flying course - and there are plenty of those that will start any time.
Best of luck, yes do seriously look at changing school, but I think you need to be realistic about what's achievable in the timescale you're aiming for. And, being frank, whether you have the aptitude to go "pro" if you've not soloed in that many hours at a reasonably intensive flying rate (I'm sure you are up to getting a PPL eventually, but the professional licences do take a significantly higher standard of flying).
