I am in a dry spell of dating and I dont see a way out. How can get more dating options?

Hello all, I am 27 yr and I am struggling on the dating scene currently. I literally have no dating options or female friends who could possibly set me up. Tbh, i dont really have friends so Im not getting invited to parties on weekends or to house events.

I am essentially a loner in my life. This did not happen by choice either. I am currently in med school where I didnt bond well with my class. There were 35 students and none of them was trying to be friends. I was labeled a nerd and no one would invite me out to the bars or introduce me to people. I tried to fit in but it didnt work out. So I got comfortable being alone.

On my own, I got good at talking to strangers and going out by myself. I did a few times until i realized that there is nothing I really wanted in the bars and honestly it was a waste of time especially since im a huge drinker. Eventually i met my gf on bumble and we had a pretty good relationship. But she broke up with me stating that she couldnt handle the stress of me being in med school.

So that is enough backstory. Currently I am in my 3rd year of med school. I literally dont have alot of time to date. I am waking up at 5 am and working until 5 pm. Im dog tired during the week to be social so that leaves me with weekends. Like I mentioned classmates arent trying to socialize. For example, i tried to keep in contact with a female classmate just to be social nothing more. She ghosted me after I asked her what resources is she using to study? Alot of weird energy in my classmates.

Lastly, my city isnt really a city with alot of social opportunities other than drinking. Plus without a friendgroup, its hard to get traction.

So do I just give up on dating and just get through med school then?
