CFA level 1 restarting the preparation

I was supposed to give my CFA level 1 examination after more than 6 months of preparation on 20th Feb’23.
But I had a mental breakdown before about 10 days and defered the exam.
How should I restart my preparation?
Any Advices?

I have my job starting in Aug and since I will be just graduating this will be my starting in the Corporate World.
According to the Deferal Policy I can go for Exam within 1 year.
So I have coming Aug’23, Nov’23 and Feb’23 attempts.
