Here the anxiety goes again..

My last pregnancy i suffered from anxiety! .. i couldnt wrap my mind around it, where did this come from? 
& now, its happening again.. im a person who wont take tylenol for a headache, let alone medicine for anxiety!! 
i would like to know if theres anything i can do to help this.. its mostly fears of me getting hurt, my kids getting hurt.. something bad happening, losing someone close to me etc.. 
last pregnancy, i literally would wake my husband & 1yo daughter up during the night and i would demand to go sleep at my mother in laws where i felt safe.. and one time i felt poisoned and rushed to the ER because i mopped floors with javex and didnt ventilate while doing so.. & mind you, the closest er room is 1 hour away.. it was crazy.. i hope it doesnt get that bad again.. but tonight im holding my family tight.. 
im only 7 or so weeks along! .. my previous pregnancy it didnt begin till i was almost half way through .. ughhhh ..
