Idk how to feel

Ok so, I'm 20, about to be 21 and I've never had a boyfriend. And I know this sounds silly, but I just get so envious sometimes when I read about women on here talking about their wonderful husbands and boyfriends and I'm happy for them, but it just makes me feel like all the good ones are taken (lol silly, ikr!). But I'm slowly coming to terms with the fact that I might die alone. Idk, tell me how you do it ladies? What are your secrets? Ps. Im on my period so I'm a lil over emotional
