Have you tried to meet any person irl to give yourself a chance ?
And coming to friends.. many people get busy with lives ..and just move on. Out of the hundreds of people..we have studied with, interacted with.. we'll have very less friends. I am an introvert and I used to have 4 or 5 friends when I was good ( now I pushed away some friends..that's a different story). And also, if that's your thing.. you can try to interact with people on internet. Like reddit, many other.
You don't know how long it goes. I have made some cool friends on internet.. one person helped me acquire some medicines, we became study buddies later. he was very helpful.
And I met another person..who eventually became a brother to me.
This is a good wayfor that. But yeah.. you need to be a bit careful since you are talking to anons.
If you want friends irl only.. may be joining a gym helps I think.
Or you want to learn a course, join in that.. you might make friends..eventually.
