What test should I take? Please help.. I don't know what to do?

iam 21 years old and have been diagnosed with PCOS last year and took homeopathic medicines. Now for the past eight months i have been suffering from panic attacks more frequently. And for the past a month i have the following symptoms:
*nervousness for no reason
*cold hands and feet
*dry hands
*hyperventilation (only when i concentrate on my breathing)
*nervousness during sleep
*acidity due to anxiety
Are pcos and hyper thyroidism closely related? i already have symptoms like facial hair, hair loss, weight gain.
What tests should i take? I don't understand what the problem is
