Never been kissed at 18?

I am on the verge of having a breakdown because of this. My best friend just had her first kiss tonight with her first boyfriend (she’s only one month older than me) and now I feel totally and utterly alone in this. I’m 18 and I’ve never had a boyfriend, never kissed, never done ANYTHING with a boy before. I am starting to feel like no one will ever want me and maybe that there’s something wrong with me. I am going off to a big university soon and I can’t believe I am going into it without ever having a boyfriend or being kissed. I wish I would’ve just gotten it over with years ago just so I at least knew how to kiss when the time comes.... or if it ever comes. I don’t know. I just feel lonely and disappointed in myself. Anyone ever felt like this or been in a similar situation?
