New city and no friends

So I just moved to a new city 2 weeks ago to start a PhD program. I don't know anybody here and my roommates haven't moved in yet (they won't for another month). I have tried making friends with my co-workers but all my jokes either don't land or are ignored and they all know each other really well and don't seem very interested in getting to know me. I've tried dating apps and did hook up with one guy but he kind of ghosted me afterwards after talking for another week lmao and everybody else just sees trash (don't respond or just wants to smash). I honestly can't do another talking phase I'm so tired of asking people what they do for work and what their favorite color is. My old friends from undergrad don't really reach out anymore because everyone's busy with their own lives and I only have a couple of friends from high school who are also busy and so that has basically left me alone. I wake up in the apartment by myself, go to work and work by myself, and come home and eat dinner by myself. This is very different for me because I am very extroverted and am used to having a lot of friends. At college I was surrounded by friends everywhere I went: at class, at work, at my apartment and when I was home I was surrounded by family and now I'm not surrounded with anyone. I know its only been two weeks but its been a rough two weeks lol I cry most days. I'm trying to learn how to be okay being alone but it's definitely a learning curve. Recently out of frustration I deleted all of my social media and I'm trying to really focus on me. Other times when I was alone I would just bury my head in my phone for hours (4+ hours a day. I know it was bad) so I deleted tiktok and Instagram. I was always sad checking my phone and seeing no one called or texted me so I deleted Facebook and snapchat. I would love some advice on how to make new friends and find new hobbies in a new city and get to know myself.
