Making friends in Cork

Hey I'm Luke and I'm 21 years old. I've always found myself being a pretty lonely person and don't find it easy to make new friends.The idea of having a group that i can be a part of has always appealed to me. I used to bounce around different groups at school but never found myself to quite fit in. I guess I'm really trying to reach out and meet new people with similar interests around my age, start fresh and see where things lead. I can definitely hold a conversation and wouldn't consider myself to be all that shy. Love to go out and adventure and explore, im happy doing most things. I just don't know where to start or introduce myself, thanks for your time!
