First of all, let me applaud your self-belief and your courage in posting a relatively long request, despite the presence of several spelling and grammatical mistakes. I understand your desperation and commend your determination.
Initial Suggestions for Improvement
My initial suggestion is for you to continue writing but to do so in a program like Microsoft Word. This way, you can easily identify and correct any spelling and grammar mistakes highlighted by the software. Over time, this practice will help you enhance your basic grammar skills and expand your vocabulary. If you read your own post aloud, you may notice that some words are misspelled, possibly because you are pronouncing them phonetically as you have written them.
Engage in English Conversations
Whenever possible, try to converse in English. Seek out friends who are proficient in English and ask them to help correct your errors. Consider joining spoken English classes and attend them regularly.
Ultimately, consistent practice, dedicated effort, and inner motivation will serve as your primary support system.
Best Wishes
