Need some help!!!!!

So I need some advice on how to get out there. I want to start dating but not sure what to do. It doesn’t help that I’m shy and afraid of embarrassing myself. The other big thing is that I am 19 and in college and I have never dated before. I talked to a guy in high school but it didn’t go anywhere since I was going to be leaving for college. I don’t have a lot of confidence because I’ve tried to message some guys from my school but they either don’t reply or message and then just randomly stop or the just want one thing if you know what I mean. Please help! I know this is silly but I could use the help and support.
