It is really appreciating that you don’t wanna hide your truth and have realization too, but you also cant forget that 100% truth also cant be accepted by anyone in this current age. I don’t care what other feel or say and about their perception about it but my practical observation, experience and requirement of this strategic, smart ages says this all.
I wont suggest you to lie but not 100% actually. And, I believe you got my point what I wanted to say here.
Second. I do not think you have no answers of their questions. You have gap in your career/education and are inexperienced (which is your status and to be considered by recruiter) that is your truth of today, and the reasons you also knows why these took place, therefore, can define them easily.
About your answer to recruiter, no matter what and how you answer to your recruiters on their question about your GAP, they will never consider it but certainly try to find potential in you and test your knowledge and understanding, which is actual job they have to perform. Every recruiter knows and can assume the answers they going to have in interview by candidates on their questions about GAP, but what they often see in candidates is lack of confidence while answering to them.
Let me ask you a basic question that comes very first and before all these conversation: Are you ready for interview?
And in answer of this question and preparation of your interview, you not just have to work for answer of this question about your GAP but for all question related to job profile/work/function (Experience, knowledge & Understanding) that you gonna apply for. And, when you will be ready with all these answers, will automatically be able to answer about question on your gap with confidence.
I have discussed the same in past with few of my friends & contacts who were at the same situation, with many members here on this forum and other, and found many answers and a lot that allow me to observe these things that I have explained here to you.
Lastly, it would be really a great help to me now I would say if you try this things in your life and share your experience with us. I believe anyone in this world can do anything what he/she really want to but need to get a CONFIDENCE which is not so easy to earn and one has to put 200% effort to achieve.
Best of Luck
