How can I 20M make friends again from isolating and abandonment?

20M I’m a 20 year old man, i’m not a virgin so I have experience of being out there, but I normally self isolate again, I’ve been recently abandoned by my closest friend for a new friend group he had similar to how my ex made fun of me and tarnished my reputation because I wanted to feel loved and feel so awkward. It feels like the people in my class are all not my type or match or I don’t feel comfortable with. How do i make friends? I try to talk to people in groups saying yeah can i go out with you? They’d delay it even if it’s a yes and it ends up not happening same with girls and dates. Everyone seems to be moving in groups, even in my small country. I sometimes go to the city center and walk around alone for hours until sunset trying to see if I can talk to someone but I get nervous. I end up staying in my room as that’s comfortable posting on instagram and trying to talk on instagram. I try to go to events as well. What do I do, I need genuine advice. I wish to travel the world, make lasting friends and show my humor, I don’t want to be enclosed as I know I have an amazing and honest true character and someone genuine like me who is not fake doesn’t deserve what i’ve been through and my family
trauma, I wish to be a father and wish to also have a girlfriend because I know how caring I can be if people tried to understand me. I want to be a good friend, good husband, good father and not always isolate. Please.
