My anxiety started a year ago with thoughts of me having a tumor, cancer etc (due to headaches etc)... all health anxiety. then all of a sudden I had intrusive thoughts about what IF you harm someone etc. Now its back to maybe you got HIV from touching the wrap that was used to wrap the guys finger which was bleeding. It only had a spec of blood and ive convinced myself I have it. I know it sounds rediculous but this is coming from someone who cant leave a water bottle out of my sight or i wont drink it for fear or someone doing something to it.
I know my fears are stupid 
But I cant get rid of them.
Is it possible for OCD/Anxiety t morph into new fears etc? First it was health then it was intrusive thoughts I was scarred of and now again health fears? HELP
