Steping into the programming world

It's been a while since college started, as I decided to take computer science and engineering. I started to feel scared and confused, whenever I try to watch YouTubes learning programming like introduction to java or python. I can't really understand. I thought I could do well. I really don't know how others are so good at it. I feel like crying. I wish I could know how to learn correctly and just know programming and how to pace each next one by one , I mean you can't just learn one programming language right?.. I really don't know. I feel lost.
