It’s still early days. Be proud that you have at least a few friends and are in a few clubs. Friends don’t just happen in a few months. There are plenty of students who really don’t get into the swing of college life until they are in their second semester. The fact that you do at least have a few people to hang out with is very positive and means that you do have the social skills needed to meet people and maintain friendships.
Don’t try to “force” your way into friend groups. Forcing anything usually doesn’t work for most things. Just relax and let things happen. I think you are going to be ok.
