I couldn't agree more with what Mr. Robin Thomas has suggested—it hit the bull's-eye. Having said this, I would like you to understand another aspect, which is the desire to pursue further education.
I'm sorry, but you haven't stated what your present qualification is. If I may guess, it's probable that you want to seek an HR specialization which you haven't pursued so far. Let me caution you: you are back in the same old rat race—qualifying competitive exams, expensive course fees, etc.
If that's what it is going to be, then I think you should aim for premier institutions like the IIMs, XLRI, TISS, and then not stop there. Go on to do research, and maybe a Ph.D., too. To become employable as an 'expert' this time around, this would be the formula, of course with a 'big' hope that you'll get the admissions, which isn't one bit easy. All this would be an investment of another 5-6 years. Can you afford this in terms of time and money? So now that you know that's what you've got to aim for, think about it.
If you have to get back to work, yes, it's not going to be easy. You'll have to try hard, be willing to be open to relocating, and also on 'compensation.' People might want to offer you as little as possible, trying to exploit your need for the job and also because of your personal pressure to take up a job as you need it for a comeback and more importantly for survival.
One Strong Advice
DO NOT WITHHOLD ANY INFORMATION ON YOUR CV AND ALWAYS BE HONEST IN YOUR THOUGHT, SPEECH, AND ACTIONS. If there is a 'gap,' so be it; do not hide, conceal, or falsify.
People like me will value you purely for your honesty and sincerity. I've been very accommodating of people who speak the truth and make an honest confession and will give them the best opportunity to express themselves so that we are able to see the person completely before we make a decision to hire. On the contrary, if I catch anyone telling a lie, however skillful or smart he/she may be, that person will never get the 'nod' from me.
I narrated this to you purely because there could be people of this nature in many other places too. I'm sure several of those experienced senior members in this community would endorse what I said.
Take care, and best wishes.
