(19M)Regret for not trying to talk to a coworker I like outside of work

I work at a grocery store, but am currently in college. Whenever I come back for breaks, I put some hours in at the store. There is a girl at work I’ve working with since last summer. I think she is soo damn fine. There are a good amount of girls at work I’m attracted to as well, but she’s different from the rest, in a good way. She’s also in college too. I’ve been thinking about asking her for her number, but a lot of things made me procrastinate to the point where it may be too late. We’re both eventually gonna be heading back to college for this upcoming semester, and I think she’s already left for college because she hasn’t been at work for the last couple of days. I’ve been hoping she would come back to work this upcoming week or I see her around so that I could ask her for her number or something, but that seems unlikely. And now regret has been flooding my mind, my body, my soul, pretty much everything within me. The tough thing is the earliest we’d both be back at work is either spring break or until the end of this college semester, which are both 2+ months away, and only God knows what could happen between then. I just can’t stop thinking about her. Now, I’m confident there are a lot of girls I could meet at my school that I could become interested in romantically, but I low-key want to wait to see what would happen between me and this girl at work if we were to not see each other until a couple months later, but at the same time, I don’t want to mess up a potential romantic relationship I could develop with a girl at school over something that isn’t guaranteed with this girl at my job. If you guys have any advice as to what I should do, please drop them in the comments below. Thank you 🙏🏾
