Your career is going to change several times throughout your life, so if you go down the law route now, you could very well not be doing it in 10-15 years time.
You need to think what is the sort of job that you are going to enjoy doing, even if the people around you are bastards, and the pay isn't great to start? What is going to give you skills that are going to be transportable to similar roles when you are looking for a change? What sort of work like balance do you want for the first few years? And what is going to give you personal satisfaction? Also, what is the easier/harder one to do first? Nothing says you can only do one. You might start with the design course, get a job, get a couple years under your belt, and then go back and study law. In fact, there's probably a job out there tailor made for someone with both skills.
