What to do when feeling fear and it doesn't stop?

I feel fear, numb, anxiety, depressed and overwhelmed. I have questions you see, in my head and since it isn’t normal to ask anything to know whats going on when talked to in my household and left to be confused sometimes other things I wish I knew what to do when I have panic attacks or what to do with the never ending confusion and fear and numbness. Is there something I should know? think? feel and can do for the pain I experience and don’t know why or how to make go away?
