Gun Classes?

I worry for my safety. In the last 6 months, I’ve had a man follow me home, a flasher follow me in Cherokee, and someone taking pictures inside my bedroom window. I want to buy a gun but I really know nothing about them, I don’t know where to start or what to buy.

Can anyone recommend a place I can take classes without already owning a firearm? Where I can learn how to use it and safety, and see which one would be best for me?
