Trying to cram such a large subject into so few words leaves glaring gaps in your narrative. What we are left with is a hors d'oeuvre instead of a banquet.

Allowing for the fact that English is not your first language, some of the phraseology is stilted and clumsy. Try to write in a more natural voice rather than one that does not sit well with you. You will find it much easier - and you'll ,learn a lot more, too :-)

Do keep writing.
