Hi, I'd like to help you with your question.
It sounds like you have panic disorder. People with panic disorder often describe themselves as constantly anxious or always feeling panicky. That is because when you are anxious, your thoughts are causing your thoughts are causing your mind to think your in danger. Your body reacts by releasing adrenaline into your system. Adrenaline causes the symptoms you feel, including the panic attacks. It is much like after you have had a bad scare like a car accident. Your body releases the adrenaline and you feel unreal, your legs turn to jelly, you have trouble thinking and your body may feel it's tingling. You just don't notice it as much because your focus is on what is going on around you. Except with anxiety, there is no focus. The only thing you have to focus on is how you feel.
It may not feel like it, but the panic does subside. The adrenaline in your system does deplete and needs time to replenish. But because your thoughts are probably always on alert, so is your body. This may be why you always feel anxious and panicky.
You may also need a change in your medication. Medications are helpful to ease the symptoms but they vary in their effectiveness. Each person has their own body chemistry and what works for one may not work for another. Also, once you take medication for a while, your body becomes accustomed to it and you either need an increase in dosage or you need to try a new medication.
The good news is that anxiety is easy to treat with therapy. In therapy, you learn to pay attention to what you are thinking to make yourself anxious. The therapist then can help you change your thoughts and therefore how your body reacts to your thoughts. You also can learn about how to let yourself float through your anxiety thereby gaining more control over how you feel. When a panic attack comes on, you allow it to flow over you without tensing or panicking in response. This makes the panic reduce or go away faster. To find a therapist, talk to your doctor about a referral. Or you can search on line at http://therapists.psychologytoday.com/rms/.
You can also help yourself at home. There are numerous resources to help you learn more about anxiety and how to control your panic. Here are some to get you started:
