HIV is only transmitted in specific ways. They include having unprotected vaginal or anal sex or sharing IV drug needles. You don't describe a risk. At all. You can not touch an object and get HIV. Air exposure inactivates the virus and this is not the way ANYONE gets HIV.
You sound like you have an anxiety disorder, to be honest. It's already been clearly stated you can not get HIV from this and fear of a volleyball or just blood out in the open is irrational. Talk to your doctor about anxiety.
