Please help

I only have 2 friends (so called best friends) for more than 6 7 years and for the past 2 years as they joined different colleges and one left ranchi they slowly ghosted me and we use to play bgmi together and travel but as the years passing they started rejecting when I ask for game or any travel.... This breaks me soo much as they were the only friend or only person I talked to everyday..... Now I'm suffering from all this and like for 2 years I'm not that happy and I've tried but I can't make new friends due to my introvert personality..... The major reason I haven't been able to make new friend is that I've joined college (marwadi college) and not even attended single class for this year as I'm focusing on content creation and business and that takes soo much time and energy of me, I usually spend my day at home at my room what should I do to get out of this suffering?
