I dont feel welcomed at ALL!

I recently began my job at Panera as a Baker girl/ Cashier. I'm a very bubbly individual. 95% of the time I'm always smiling regardless of what im doing.

My coworkers are okay but I'm just getting the vibe that I just don't fit in now that I've finished my training. It's been 2 months since my training ended (so almost 3 months). Im there almost everyday except weekends. It just feels like nobody likes me there or that I'm not welcomed at all. Am I overthinking it? Should I give it more time? Or should I just focus on my job and not my work environment? Help
