If I find CS50 too difficult, will I dislike programming in general?

I was hoping to build an app (just for fun). I’ve been doing CS50 and am finding it tedious and difficult. Is programming not for me? I thought I’d find it fun because I as a kid I made pretty decent websites with HTML in Notepad, but so far I’ve just been feeling like an idiot and not really enjoying it. Solving the problem sets doesn’t come naturally for me, and I have to google endlessly to make slight progress. I liked the JavaScript course on Khan Academy, but that was a bit too far in the other direction (a bit too easy/babyish).

No! CS50 is focused on C programming and some people find it hard to grasp the idea of low level programming. 
As you said you like JavaScript, so continue developing with it. If you like front end stuff with html, css and JavaScript just do that. If you also like back end, check out nodeJS. 

Take small steps in learning programming. The best thing that works for me is learning by doing. Try something and if you get stuck watch tutorials and Google a lot. Also don't be afraid to ask.
