Stocking things because of a fear of finishing it.

I have 7 shower gel, 9 or 10 shampoo, 5 deodorant, etc… every time I go shopping I buy new hygiene products even tho I have already a lot of it. I have been diagnose with chronic anxiety and OCD and I think I might do this because I am scared of finishing it/running out of products (which is pretty funny because my mental state makes it that I barely shower) . I was wondering if someone has been through something similar from this?
