Lugs symptoms and conditions

I have been on advair for about 4 years didn't know till reading all of this that it could be the cause! My doctor urged me to not stop taking it! I have stopped about a week ago now my symptoms are worse than ever! But I hope will subside! I have recently developed the foggy head, changes in my lugs , chest pain, anxiety panic attacks heavy breathing worse asthma attacks I am 31 and also have osteoporosis now do not know if it is because of this and they think I my have copd I also have infections now that last forever can't concentrate etc. and I have 3 kids and a full time job had 2 take off 2 months! Do not know if I will ever be normal again I hope so! Too much pain and cramps as well just cant understand why I have developed these things later and why they are wores now that I have stopped?
