On the basis of what you have posted above, I do not recommend that you become any kind of lawyer. Bibachu has asked you sensible questions about why you want to become a lawyer.
It appears that you may be unfamiliar with what lawyers do. Fictional lawyers in TV shows are rarely shown reading or writing, because those things are not as televisual as court hearings, client meetings, and office politics, but in real life lawyers read and write a lot.
By the way, a GDL is not a law degree. A PGDL is obtained by studying the core subjects within a law degree over one academic year. The qualification awarded is a Diploma. This doesn't matter in your case because, unless you change your approach to reading, writing, time management, and complexity, you would be wasting time and money if you sought to qualify as a lawyer.
