失望了

I have put myself into desperation~
I lost control and I indulge myself to do all those stuffs I am not supposed to do right now...
I know that It is time for me to concentrate, but it seems like a mission impossible for me : I can't focus for more than 15 minutes even in my normal conversation with other people....T.T..can I say that I am not sincere and put in my heart in all of the things around me?
It is my onus to pay attention and live my life to the fullest.....But I cant even achieve anyone of my goal....
真的失望了，是我没那份心？还是我根本就把我的心遗漏在某个角落了？
能从拾那颗被我遗漏了的心吗？
你在哪里？
还有你的理智呢？
