Your bike is pretty shite, but with a little work it'll ride decently enough.
Check out the BQG thread, and also look up bike maintenance tutorials on YouTube. RJthebikeguy is one of my personal favorites, but there are countless other channels you can find help through.
Look up "adjusting brakes", for starters. Your issue could be the brake pads being messed up, the brakes themselves just needing to be adjusted, or perhaps even something with the cable or brake lever.
You'll be able to do most of your own easywork with a crescent wrench and set of Allen keys.
You should be intelligent enough to look at the issue, troubleshoot until you figure out what's causing it, and go through some trial and error to fix it.
Good luck, and keep riding your bike.
