sophomore cob sorority rushing

Hi. So I dropped rush as a freshman and have been very unhappy. I dropped because I was left with phi mu and really can't see myself in that house, not because of its reputation but because I really don't fit in with the girls. I wanted to hear your advice on what to do next year. I'm really struggling with having friends and feeling a part of something even though I go out all the time I still feel like kind of unhappy not being in a sorority. Should I fall rush and then if I have to join phi mu just for the sense of being in a sorority? Or should I rerush in the spring? Rush this year was so brutal so I'm really not feeling rushing again in the spring but if people think it's a better idea idk...
