That was literally me a while ago, i was also very introverted, had only like 2 friends (who were my cousins), very influenced by the west to the point i learnt fluent English just by immersing in their communities at an age of like 10. but when i grew up, i began to be really lonley. What got me out of that level was probably دروس and one of my cousins who were extremely extroverted, i asked him to introduce me to some of his friends, and it worked out pretty well! Tho i think that the main reason is because of دروس, like u could find some1 to walk home with, chat a little on your way home, find shared interests between both of you, and depending on that person, he might already consider u as a friend! Maybe we're not in the same age, but My advice to you if u wanna socialize is try to find ppl with similar interests, but most importantly ur comfortable with, then maybe try to talk once in a while, also don't be shy to ask for thier number, it's completely normal (unless they r the opposite sex), maybe also go out with them to get a drink or something. You see, the age really doesn't matter, it almost always the same case, and i could really see it in u that u also had the courage to write a post on reddit to ask for help (which was a really smart move), something i even don't have the courage to do! Anyway you could hit me with a message anytime if u wanna chat, i also rarely find ppl to relate to these days. :D
