I need new friends

so im having a really hard time making friends in college, its been like 3 or 4 months now and I still have like no friends!!! I was originally friends with this girl Ashley and all of her dorm but she started to get close to this girl in her dorm and now we dont hang out anymore, I still talk to some of the people in her dorm but their boys and since Ashley doesn’t call me anymore I don’t really see the boys anymore. when I see the people from her dorm they all ask me where I been but I don’t know because I dont just want to be friends with a bunch of guys im a girl. Then I started to talk to my roommate and I still do talk to my roommate but shes always either at home or talking to the boys downstairs, AGAIN the whole boy thing I want girl friends! her friend from home lindsey lives in our dorm well lindsey doesnt like me so whenever lindsey is with us at dinner and lindsey is done eating my roommate will leave wth her and leave me there. or lindsey will ask her to go to the mall or something but I wont ever get a invite. Lindsey, Lisa (my roommate) and Jordan( lindseys roomate) always are together and go places together but I never get the invite I like jordan and tried to be friends with her but the whole lindsey situation isnt working for me, there are other girls down the hall that I want to get to know but I dont know how I should go about doing it, see im really shy and its kinda too late to be like hi im Jayla because they already know that, I never had a problem making friends in highschool I dont know what the problem is now!!!11
