Uncontrolled thoughts and emotions

It is not easy for me to accept the bad in me. It is difficult to be not emotional and sensitive about small things these days. To accept the bad and good in me as a part of being human that has fallen. It is difficult to express thoughts in words. I want people to see me as good but then it is to deny the bad inside me as well. When others told me to take it easy not to think it so hard and so complicated, but my heart say no to it...When others say I should open my heart...I don't understand how could I do it? What is specifically opening my heart means...how should I do it? Why I should I pick up every little things and make it big?

I feel helpless at times and hopeless most of the times, especially when I fail with this uncontrolled emotions and explosions of anger....

But then..I remembered God is still working in us...then this help me to calm down...
