Some people are biologically more susceptible to anxiety. A lot of people say "man up" or "stop being a bitch", those people are ignorant. It's incredible hard to control anxiety attacks, you would need to change the chemical reactions in your brain.. can you do that?
The best step is to take medication that will keep the attacks from getting out of control and then slowly over time you can learn what triggers these attacks and how to manage or prevent them from starting.
A few other home remedies you can do that will naturally help fight against anxiety is working out, eating a more balanced diet, and getting plenty of sleep. I've found that working out helps a lot, because for one it takes your mind off stressful things, and two it induces chemicals in your brain that help your relax and feel good.
