Hey guyz... me pusuing BTech and got failed twice in first year... got very depressed... life become just hell.. dont know what to do... from now..?

I'd consider picking a different career path... something else you have an interest in. If you failed this one twice... its not for you. Many people have the revelation they need to pick a different path once they have embarked on one. You aren't the first and won't be the last. And many have never been happier once they have.

What do you want to do? Why do you feel this is happening? Is it related to your not understanding the syllabus or you have some other tension in life? Do you want to continue or leave? Explain your problem then we can guide you..
