SMU sorority dirty rush

I cannot rush until next formal recruitment, which is fall of my junior year. And apparently it’s even harder for juniors because they have a quota for sophomores but that doesn’t apply to juniors. Also by junior year it doesn’t matter at that point. I just want to have friends to hang out with outside of school who I feel like I really click with. There are people I want to get closer to but they already have friend groups and sororities are exclusive if you aren’t in theirs. The people that have been easier to meet are just not my people at all so I’m not sure what to do. I feel like freshmen have more friends than me for some reason. Also I’ve always dreamed of being in a sorority so not being in one I love isn’t really an option for me. Also if you aren’t in a sorority or are in a bottom one at smu, you don’t get the same type of college experience. Like I’ve always dreamed of a certain college experience and I’m afraid I won’t be able to experience just because I haven’t found my people yet, everyone else has and are clicky, and I’m not in a sorority that I fit in. The main reason I wanted to join a sorority was to find life long friendships with girls who are similar to me but that’s not the case in my situation.
