How to draw closer to Allah without much knowledge

I am a woman brought up in Christianity. I have learnt a little about Islam. I am writing to you because I am concerned about religion. This uncertainty is affecting me in a negative way and I am fearful because I do not want to go to hell or dishonor God. My greatest desire is to please God and to do His will. My question is: How do I draw closer to God if I know so little?
