Collecting things is normal for a person. But would you believe that i also collect insects? When i was a kid i collect insects and store it in a small jar that my moms display in the living room. When i woke up in the morning. I collect dead ants, i place it in the jar. I can count that it has thousand of dead ants are there, everyday i notice that the jar is not fulling up so i stop collecting it.
Don't consider yourself as weird, because lot of people were doing it as profession and hobby for research purpose but you don't have to let them die.
