Things that i done cant achieve the best

From the time when i say want change to my last time that me and from there i start to change and when the time past all my things that i done previously all was burst in at one time and from there i want to make thing the best in my life but I don't know I cant do and make it the best. I really wish to go back my last time and there are many people like me and dote me. Seriously, I really don't know how, what I can do to make things the best.  I just want my life back to last time and win some one heart back to me.  This is because I really i want to find back last time those happiness we have but is now her heart is with other that why I choose to give up le and Now I just want to do things is right and people think i am not useless but things that i do people make things i am useless.  No matter what i will try my best wont give up easily which is my last time that do things wont give easily..
