Tried to talk to a girl and failed...

Tried to talk to a girl and failed... I met up with some of my friends today, and there's one girl in the group who I like a lot. It's not that I was extremely nervous, like when I have to present in class, but I stutter so much around her. Still, I tried to keep the conversation going and be a fun person. I don't really feel bad about myself like before, because it's just how I talk. When we were going to walk back I suggested "let's walk to ___'s house it's close" and she made fun of me, saying "yeah l-l-l-l-let's walk back" (I have more trouble with l's) it made me feel really embarrassed...especially how some of my other friends laughed too- just wanted to share, I'm just feeling kind of down
