Anxiety and Panic Attacks?

I have bad anxiety and panic attack very long story short, I Do panic attacks all days and I see my doc to try to get figured that must be taken. So my question is how do I explain to my boyfriend that this is not just something you can turn on and off, and how it feels to have to go through something like this.And also how it feels to have a panic attack. He thinks he can turn on and off, always says "All will be fine" or "your right" I just want to explain how he would feel if you were in my shoes. We greatly appreciate all the thought that I will to try.
