Once again my stuttering has driven my mental health to the floor

Once again my stuttering has driven my mental health to the floor I got assigned a three day job in college helping with a fair. In my work group there is a girl, she seemed pretty interested in me, was smiling when we were being introduced, asked me to work together. We kinda had good chemistry, I did some good jokes she laughed, all that. During the day I did my best to not stutter and mumble but I could clearly tell she was really slowly losing interest, didn't like the way I spoke, by the end of the day she just kept nodding to what I told her and pretty much lost all interest she had on speaking with me. Today it was the same, she wanted nothing to do with me and now I just wanna throw myself into a hole
