A friend turns into a foe.

We all have friends and we used to share each our happiness as well as sadness to them. Friends are most important in our life as they are the ones to whom we can share anything in our life. Friend is need is a friend indeed as a famous thought for us. I used to have most of my friends who were good and some were bad in terms of nature. I shared my all thoughts as well as what is happening in my life with one if my friend. So my friend keeps on supporting me and give me guidance on each day and I was like blindly following his advice as he was understanding my problem and shows me that he is supporting me and will keep as confidential. But I don't even know that he was the one who was passing information to other friends and even things which I shared to him , others were reacting the same things as told by him. I felt angry as if why do I shared such personal problems with him. Even he was making fun of me. Instead of only ignoring that person, I ignored all my friends as I thought that they all are same. That friend was doing such things and now all are my friends are with him and no one is supporting me. 
It gives me a huge lesson that we should not discuss personal problems with anyone or the outsiders but with our family members. We should ignore the behavior of one person who was behaving bad with us and instead we should talk with others and avoid that person. Never expect others to help you, we should help others. Never judge people by their nature and the way they are.
