Hi Crissy!
I do not think it sounds weird at all what you are describing, most of us anxiety sufferers have irrational fears and obsessive thoughts, they me be different for each one of us, but it in the end it is all the same: A symptom of anxiety.
Keep posting here and feel free to share with us what you think other will not understand, chances are we will! You will get a lot of support here.
I agree with Hibee, therapy will probable help a lot too.
Hugs,
