In addition to the great advice from Mz, I'd say that the first year of undergraduate is more about "learning how to learn" than anything else. It's likely actual real life applications are going to be less relevant in that first year (which is perhaps where your strengths currently lie, and at this early stage in your career that would be an exceptional string to your bow even if not so helpful in the first year).

The reality is that the theory can be important, but also if you flunk some theory courses but are great at the practical applications that's actually far more valuable than the converse (unless you're hell bent on going into a more theoretical branch of CS). If there are elements you're really struggling with I dare say there will be people here and elsewhere on the webz willing to lend a helping hand.

Stick with it. Don't believe you're too stupid - you're not. Nothing is difficult, things are just complicated, and it's all about taking the time to understand that complexity and it's components to make sense of it all.
