it`s too near to think about?

You haven't given us too much context to work with, so this is more of a guess than an answer. In this case, I don't think that "near" means "small" or "painful." It may mean something like "close to." Also, are you certain that the word is "near" and not "dear?"
Could you provide more information about the passage or paragraph this came from?

thank you for your willingness to help me trough it, more regard to the part of the contex. : " I know how to cure them rather easily. Maybe I´will never let be done. For had they had their way we would have lost our chance . It is too near to think about. After all, we have to earn our freedom. I don´t care so much for those who didn´t help The rest of us had to sweat a lot harder than was nece

I still don't feel that I have enough information, but I do get the feeling that the author wants to convey a sense of proximity (either physical or spiritual). I also feel that this is not very well written and that the choice of the word "near" is not the best.
It seems as if the author is speaking about an event that has occurred and that is still too fresh in his mind to think about object

I do not think these sentences are well-written. Awkward tenses and word choice. From what I can decipher, I believe "near" may mean "soon" or "recent" in this case. Meaning, something has occurred, but it is too soon to think about it, evaluate it, or reflect upon it.

Thank you very much for your answers, this is from a book about the way to freedom and about some people who would like to prevented only chance to that freedom, you can consider that in this context.... Can be chance "near"? Or thinking about the lost chance is too "near"
(intimate) to the author to consider it?

Yes, I'd say that is what the author means.
Is the author a native English speaker?
Is the book a translation?
This may or may not explain why we feel that the piece is not particularly well written.

I agree it is rather exotic, the writer is a native speaker from 1960, me not, so your help is really appreciated.
But I do not quite understood if it is

Here are two suggestions for rephrasing that I feel might be of some help. As you say, this is a rather exotic piece.

For if they had had their way, we would have lost our chance. It is too soon to think about this hypothesis.
It's too soon to think about whether or not we would have lost our chance (to do something) had they gotten their way.

thank you, so it means that "near" in that sentence means the most probably "too soon" ?
