Degree Extended. Feeling lonely. What to do?

Due to Medical reason, I had to drop out of one semester and due to pre-reqs/even-sem only courses etc now my degree has extended by an year. I left society clubs and socialising because I always felt weak and tired due to medicines, health etc. But now with my degree increasing I feel more lonely than ever. I regret it. 95% of my own batch people don't even know me now. I wish I could just talk with some random people sometimes but I fear judgement. I wish I had put effort during my first year to meet with people and make friends. I did make some friends but never talked again. Wish I could talk with them offline before they leave forever, but can't get the courage. I wish I had people I could talk deeply with. Or maybe even philosophical and not only course related. I will sit placements in 2025 but I don't even have idea of most things because I don't have people to talk to. I had single room my whole hostel life so don't have good hostelmates either. I didn't do internship either. Or joined any competition ever. Most clubs are now dominated by juniors and I feel embarrassed to go because I think they might judge me as a loser. And than judge me again on poor skills. I already look ugly. But I cannot cry myself everyday to lonely life. I want to make friends or people I can talk too. Please suggest clubs or ways I can figure it out.
