Sapana, O chem IS hard! My prof assures me that lots of people struggle and that is it difficult for most students. It requires a good deal of study and practice that is well beyond what is typically needed. I am taking it as well and we are working on carbs right now as well. I have to work on it every single day.
What specifically are you having trouble with? Have you tried to get a tutor or joined a study group? Sometimes that can be more helpful than anything. Try to make sure you read the material before class, then again after class. You might also want to invest in a recorder to record lectures. That helps me a lot.
Here are some websites I have found useful:

Hang in there. You are 1/2 way there, you can do it. Let me know if I can help.
