Fear is normal, though sometimes because of that fear i get too lazy to start to learn something new. So just think positive, nothing is impossible.
Maybe my advise isn't so good but i like to buy new pens and have some sweet stuff like chocolate. If i pass first hard part i can encourage myself with a bar of chocolate.
No problem :) out of curiosity what do you currently use to learn web development? Something like Sublime or VS Code would be good options if you're looking (I recommend Sublime but it's up to you).
Check out the book Head First HTML and CSS. It gives you a great foundation and is interesting to follow along the way.
Get a basic hosting account, register a domain, learn how to setup a website use FTP.
Next go through the book Head First PHP and MySQL, it will give you a basic foundation in forms and databases.
After that go through Headfirst Javascript, then Headfirst jQuery.
Signup for a github account, checkout ways to deploy websites without FTP, explore Vue and React.
At that point you could start learning frameworks like Rails, Laravel if you want to create web applications. Pick out something you need/would use, it will make it more interesting.
I will strongly suggest freecodecamp as well. Try to complete it without looking for solutions on Stack.
Alternatively, if you're looking for employment and you're in the countries where Lambda School[0] operates, that's a really great option for you to explore.
