Sorry to disturb you with question .Please what do you think of writing style?

Is English not your first language? You have a lot of trouble with staying in one tense. For example, your 3rd sentence "Many times I used to hear them saying that I come to this world by mistake..." This sentence could be improved by first of all keeping it in the same tense. "Come" is in the present tense, but the rest is in past. Also, instead of "saying", you should have put "say" to properly complete that phrase. Go through and look at things like that. Mainly you need a grammar check throughout. If you have any English speaking friends, they can help you word things less awkwardly. And I applaud you for being able to write this much. I'm almost fluent in Spanish, and I understand how hard it is to learn all the mechanics of a new language
