Struggling with a crush

Hi, hope you guys are OK.

I don't know if this is the right place to post this, but I just need to let it out. (Also, it's a bit of a weird situation so... bear with me)

So, I started college this year and met someone I fell in love with, they're already in a relationship, and I'm having a hard time getting over these feelings. Obviously they're not reciprocated, but honestly I can't help but feel really bad when I think about it. There's also another person in our friend group that's chasing after them (despite them having a partner) and I think I'm starting to feel a bit jealous about that, even though I know I shouldn't be feeling like this in the first place. Sometimes, I even wonder if they like me as a friend, which would be fine by me but it doesn't feel like that is the case and they probably hate me or think I'm gross. at the very least.

So, is there any way I can get over this situation? I feel like it's eating away at me.
Thanks in advance, and sorry for the inconveniences.

Is it necessary to struggle?

If you habe a crush on someone and that person doesn't reciprocate or even notice you, just try to forget that person.

I’ll just comment on the person chasing after them; either it’s not going to work and that person looks like an ass, or it will work and the person you have a crush on is not worth your time.

It’s easier said than done, but don’t worry about the other person pursuing them.

I wish I had something useful to say about the rest, aside from the fact that the way you think this person sees you may be very low self-esteem and not based in reality.

If you really want to be with this person, then getting yourself in your best physical and mental health will give you the best chance of have a successful relationship with them.

So they are in a relationship now, but if that doesn't work out, maybe you'll have a chance. You've got time in between now and then to work on yourself.
