Work for another company if this one doesn't work for you. Don't generalize the whole industry or career path just because your current company is lousy.

You are just asking for trouble if anyhow jump into banking and accounting when you don't even have any knowledge, interest or qualifications in the first place.

Your qualifications will not get you anywhere near the lucrative parts of banking, most likely end up either in back office operations or retail sales. These are long hours & repetitive jobs that are unlikely to fit someone from creative side.

If you go take CPA/ACCA now you will just end up as a "too old" accountant without any relevant experience. Chances are you will be doing entry level work in small auditing firms or book keeping in SMEs. These are again unlikely to be suitable for you.
