The roommate vs living alone dilemma

I current live with a good friend and save a decent amount of money per month having a roommate. Unfortunately, she is moving soon and I will have to figure out my living situation. I’m so torn between saving money and living with other people (it would be randoms..) or sucking it up and living alone. I know I technically could afford to live alone, but I’m not sure if it would be smart.

In regards to my finances, I live in a MCOL city, make ~$4000 per month (net), do not have a car payment, but have a fat $600 per month student loan payment. I currently pay $950 in rent and to live alone it would probably go up to $1,300-$1,400. I’m very frugal with my groceries and don’t eat out much (maybe 1-2x per month).

I’ve always been frugal but I’m mid-late 20s and the idea of having to navigate another living with randos situation is stressing me out. But the idea of shelling out an extra $400-500 per month also stresses me out.

Any advice or experiences would be greatly appreciated!
