Everyone reaches a point in their life when they think they have failed in every aspect of life, when they start to doubt their capabilities, when they find themselves at the nadir of the otherwise hopeless world which doesn't seem exactly welcoming to them. A point where every thing you have done before seems nothing and what you are expected to do now is either beyond your reach or is completely clueless. I won't say all people at some point in their life feel so but many of us do, and what we need at this point of time is a refill of confidence and support which only our friends and family can provide us with.
At such a crucial stage of life we need the support of our closed ones, people who have known us from the start and who know the things we are capable of, who still have hope in us. A hope that says this is just a rough patch, you will get through it and strike again with all your might and eventually you can get whatever you want. We need people who can help us find out the path which we have so efficiently missed. Only such love and support can get us through this and help find the right chosen path for us.
But what if you reach a low point in you life and people around you are determined indeed to make sure you feel all the more depressed and when you doubt your capabilities, they make sure you realize you have none. When the people you trust the most to help you come out of this situations are the people that discourage you the most. Tell you at all point that "you are nothing and we are all better off without you to worry about". Life doesn't seem any more fair and just leaves you with a choice to make - Either work double hard and try to convince yourself and others too of what you are worth of, or simply accept the fact that most of the people who know you the best, that includes yourself and your family, think you are worthless, what more is required to make it official- you really MUST BE a good-for-nothing jerk who has really let down everyone including yourself.
