Really need advice!

Ok here goes,Its another long post but I am so hoping that someone can give me some insight here cause I really do feel like I am nutts.OK back in 2005 my hubby at the time he had gotten really sick he was diabetic high blood pressure,then he got colon cancer.so after yrs not takin care of hisself he got put on kidney dialysis.So he wouldnt comply with the dialysis he ended up havin a heart attack and he died,but they were able to bring him back,BUT he was brain damaged from it.ok I know your wondering why I am going in to all that,just trying to give a some insight on what may be wrong with me,After the fact that he came thru I had a real big time trying to take care of him,He was like a 45 yr old kid,well soon after he came home from the hospital I found I was pregnant.I FREAKED!! not because I didnt wanna baby but I was wondering how in the world I would take care of my hubby and a child.So I ended up having to put hubby in the nursing facility.I had my baby.well soon after having my son,he was 4 days old I just knew I was having a heart attack.I had to call the ambulance thinkin I was dying.I get to the hospital and low and behold the very doctor that had worked on my hubby when he died was the one I got,He come in and said you are seriously stressed from your hubbys illness and u just had a baby,you are having severe anxiety so he drugged me with some ativan sent me on my way.well then I kept on having it so I went to my OBGYN come to find out it was where my body was tryin to level out from having a baby.OK good so after several months of that hell I went thru,I thought that I was pretty much normal again.so a couple weeks ago outta nowhere I started to have the hot flashes couldnt eat thinking something was serioius wrong again.so like before I went to 3 doctors they asked have I been stressing?I am like well I had been trying to help my brother who had been diagnoised as paranoid schizophrenic he was going thru a tough divorce.but it got to be too much one me I ended up having to send to another family member.when I told the doctor that she said I was having anxiety due to all that stress,So my question is can it hit you just like that without warning?I mean really could understand the reason I went thru it after having a baby and all.I just scared most the time and it hits me alot and I try hard to talk myself thru it.I am sorry its so long but I just thought if anybody could see what I went thru it might help shed some light..if you read this thanks so much for taking the time,

Yes. It can hit you just like that.   You live a very stressfull life.  I would recommend you see a therapist to talk too.  Once you have had anxiety you can get sucked right back in really quick.   The reasoon is because you fear the symptoms of anxiety.  Once any new symptoms come upon you, you start to concentrate on the symptoms, thus setting the waves of anxiety through your system.
