Traveling alone and scared out of my mind -what do I do?

I’m traveling to present my dissertation. I’m traveling alone since my husband couldn’t take time off of work, and I didn’t think it was that big of a deal since I lived in the city for half my life. I also stayed in the specific hotel before (which was a traumatizing story itself lol).

However, I’m just freaked out. It’s one of those budget motels (slightly higher than Motel 6) so I wasn’t expecting much, and most recent reviews said it was ok so I thought “wow maybe it got nicer”. Well no, the first room I got had a really weird stain on the bed, and the door lock was gone. Thankfully, the guy at the front desk gave me a new room and it’s way cleaner but still. I’m also just terrified of the people around here. The city itself is one of the safest cities in the world but there’s so many sketchy people in the hotel. I didn’t think much of it until a review on the 3rd or 4th page was complaining about the police being called multiple times a week, and people knocking on random doors looking for drugs. Now I’m freaked out. wish I saw that review before.

What do I do? We were fine last time we stayed but I am alone this time. I also forgot the door hatch key lock thing at home, and can’t afford a new one. This hotel was already out of our budget. I can’t afford another hotel either. I would’ve stayed with friends but their roommate said no. Am I being dramatic?

ETA: I will add that I have seen families in the hotel. So maybe I am exaggerating? It’s one of the safest cities in the world so idk.
