You are going through a lot in your life. You are hit by failure by failure. You don't have a damn thing in your life to be proud of. And nobody cares for you.
May be, I don't have a right to advise you. But I dare to say a few words. As I also had gone through some stuff, maybe not much, but I had this feeling too at some point of time. Then how did I cope up with?
You are suffering, I am suffering and everybody is suffering. Maybe you are suffering more. But believe me we don't have a damn idea of what others going through. So you are not the only one.
At this point you can be sour towards life, or you can keep moving as you are. Yeah, that's hard. You don't feel you can do it. You have to do something to compensate to your feeling of loss. You will put everything you have to do that.
Now believe me, if you put that energy in living your life you can be no less than the most successful. You have to kill yourself, with the truth that everybody is fighting for their good place in this world and no one is awarded easily, and live.
The more we go through stuff the stronger we become. You would say I didn't asked for it. But believe me if you have not gone through enough stuff and become harder(stronger) to live your life, you will definitely regret for those days that you didn't suffer and not learned anything.
You are never a failure or everyone of us is a failure.
