Re: help me in writing a letter
You need to use complete sentences that end in periods/full stops and break this into paragraphs. What you have is a rambling loosely connected set of phrases that is simply exhausting to try to read. Also, use real words like "because" instead of text-words like "bcoz" and check your writing so you use the correct word like "no" instead of "know."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
