I am 36 yrs old and lived with anxiety all my life.. Started in my teens.. It's been off And on.. But the past couple of months!! I cannot shake it!! It's shaking me.. I started seeing a therapist.. I come to the conclusion I am afraid if dying!! But I cannot control the thoughts when they start.. I understand what each of you are going through.. I thought I was alone with the physical pains.aches,dizziness..head full of pressure,can breath it is very debilitating..
