Message me. I would be happy to help you. But it can take years to get to a point where you get to that stage, but it's rewarding, it's not something to persure without a passion.
And I'm sorry to break it to you, ICT and computer science sre 2 completely different fields. But don't let that put you off.
The people that are most successful in computer science are observant, naturally curious and is good at finding ways to solve problems. (don't worry if your maths isn't up to much)
Get used to not giving up in finding something, not everything is going to be spoon fed, it's mostly up to you to find thing's.
Your best off starting with something web based (HTML, css and Js) and look into making a basic PWA.
Then once you've mastered that (should take about 8-14 months - although it is not something to be rushed just let yourself go at your own rate)
Also on the way have a look at SEO
then start having a look at PHP and SQL, Start looking at some open source PHP scripts other people have made, some people click with it, and some people don't so that could take anywhere between 2months and 2years. It's also worth investing in some cheap web hosting, you can get it from ifastnet.com for around £3.5 a month
At that point you'll be able to make a Progressive web app with database functions and hopefully even a nice UI.
At this point I would recommend moving onto proper apps using java, but by this point you'll know what you'll want to do anyway.
I used a lot of abbreviations there, there may also be a lot of terms you are unfamiliar with I have done this deliberately this is so you can get used to searching things on Google, as you'll have to do this a lot, you might even have to go as far as page 10 sometimes.
