Well since we all have some sort of psychic abilities it can true practise be developed, and I am sure someone can give you good advices on that.
But since you tell that you have real problems affecting yourself and your children I wonder if you must concentrate your effort to solve that first.
Problems occupy most of our thoughts and and it will be hard to learn anything.
What you need to do is to sit down....evaluate your problem as good as you can....put it down on paper.....then when you think you have the view on it...try to focus on how to solve each bit of it. Many times a big problem is the sum of several "lesser", each of those "lesser" you manage to solve...make the big problem lower.
If we only see the big problem, we might give up because it seems so big.
Stay positive....that is the most important task....many times hard.....but it is the only thing that helps you without costing anything.
Good luck to you
