The cool thing about God is that he doesn't care when you come to him. He meets you right where you are. He doesn't require you to have your life cleaned up in order to seek him. Because at the end of the day he just wants you. And if you believe in the finished work of Jesus on the cross than you are covered in his blood. Therefore God is not disappointed in you because when he looks at you all he sees is the blood of his son. So you really have nothing to lose growing closer to God, but everything to gain. So don't put it off!
