It really just depends. Therapy is great, don't get me wrong. It saves a lot of people. In my personal opinion though, no one can change us but ourselves. A therapist can help cope with emotions, but until you put the work into it you're probably not going to get better. Unless you are diagnosed and treated with medication, but even with that some work has to be put in.

There really isn't a right or wrong way to do it. There also isn't a set way to take care of it. It's something that you have to tell yourself can be controlled. You have to find your own ways of coping with things. I am generally pretty laid back even with my anxiety. My anxiety has got much better with my own help. I have learned to do things during anxiety attacks that make me feel better. For instance, I will take a drink of water during a severe attack. For whatever reason I have led myself to believe that water cures my anxiety. Which is what anxiety is to begin with, a condition in which we allow ourselves to feel like something is happening to us. It is completely real, but in a lot of instances brought on by ourselves. Just as we can lead ourselves to believe that something is happening to us during an attack, we can also lead ourselves to believe that something is curing it, or fixing it during an attack.

It really depends on the person. Therapy would be a wise decision. The rest is something you'll have to work on. Find ways to cope with the attacks. If you can bring your anxiety down, you can also lower your stress level which in turn will allow you to feel more relaxed. I used to tell people during my extreme anxiety years that they were crazy when they would tell me "you have to tell yourself it's going to be okay", but it honestly works. If you can tell yourself it is okay and tell yourself you are relaxed and truly believe that in your mind then you can work wonders for yourself.

I wish you the best during this difficult time.
