Severe anxiety. Please respond

So for some odd reason I have this irrational fear that I am going to develop leukemia or already have it. I know this is solely caused by anxiety. I should mention I am an extreme hypochondriac and the only thing that 1000% clears my mind is a doctors confirmation. I have anemia as well. But for a long time now I have had that fear and i think about it all day everyday and I feel like it’s ruining my life and keeping me from enjoying my pregnancy...... nothing seems to clear this from my head. I feel like it’s due to having (undiagnosed) Anxiety, plus hypochondria..... why am I like this?? I want to cry all of the time because I’m truly SCARED. I’ve always wanted to get this off of my chest and tell someone........

I’m not even sure if I have anxiety or have developed it over the years being the hypochondriac I am. I can be just doing nothing and all of the sudden I get this scared adrenaline rush and sadness feelings come over me out of no where and I start thinking about that specific fear.

I just want to get blood tests done to help this fear come to an end.

Please don’t judge me. I’m not sure where I should have posted this but I just need someone to talk to about this.......that will understand me......
