you won't get funding for a psychology degree if you already hold a degree... you should also be working in the field if you're considering changing career direction entirely as psychology can be a really long road to holding a job in counselling/etc so you should be sure you'd enjoy it
have you considered something like art therapy? no idea if you'd qualify with graphic design (you'd still need work experience) and you'd still have to pay for the MA but you might be able to take out a career development loan or something
