Hello and welcome to the forum! A lot of us have anxiety so you are not alone. I think that is a great idea to tell your man. If he is a gentleman he will accept you for who you are help you with your struggles. Talking about anxiety can in itself induce anxiety; however, it is the first step to conquering it. Keep us posted and let us know how you are doing ok
I really feel for you, my wife and daughter have it, being honest with him now I think really important, make sure he knows just what triggers your anxiety, best he finds out now, it wasn't till my daughter was diagnosed with it that I put 2 and 2 together about my wife.
