Nervous to start jiu jitsu cl?

I have REALLY low self esteem. Like I'm VERY self conscious. I'm a girl who really wants to be an MMA fighter when I'm older. And I want to start taking jiu jitsu cles at my gym. I already take the kickboxing cl so now jiu jitsu. I will be going to the kickboxing cl first then stay at the gym for an hour until the jiu jitsu cl. The thing I'm nervous about is that no one will want to roll with me in jiu jitsu cl. And that I'll smell bad. It's one of my biggest fears that no one would want to work with me.. I'm scared no one will like me. I'm also scared I'll be all sweaty by the time Jiujitsu starts. Can anyone help me? Give me some mentorship? Thanks.
