I'm shy how can i make new friends without making a fool of myself?

Im a really shy girl and i moved to this town almost 2 years ago, I attend a technical college so the days and hours are weird. I can make conversation but nothing enough to get someone to stick. I dont wanna make a fool of my self go up ask them to be my friend and them say no. plus alot of the people are older then me in my classes.. alot older like in there 40's im 20. so can i get some ways to make friends without makeing me feel weird?
