Credit card

I only have a secured one, and I only got it to build my credit and have for emergencies, but was wondering if I should apply for a real one. I’m low on cash tbh, and I could really use one. I have had a few emergencies unfortunately come up, (dental bills and car had to get fixed) and would easily be able to pay off $200 next month and my credit is decent. Any suggestions?

Ok, I was just wanting to get one for a little bit of money to get like $30 worth of food.
