English people please help?

My greetings to all. First off, I'm very weak in english grammar. I've been trying hard to the best of my ability on how to construct a sentence with few errors. It hurts sometimes that my friends speak in english fluently as well as writing skills. Can you please give me some tips for me to learn as far as grammar is concerned?..If you found some errors in my statement can you also correct it for me please?..Thank you so much:)
