I eat panties, will this make girls think Im weird?

You may have heard of men that like to sniff panties, well I take things one step further and actually eat them, but only if they have been worn by a girl and have not been washed. I think I may have some kind of mental issue that I really need to get sorted. My girlfriend went to the toilet just after we had , when she came back she asked where her panties where. When I told her I had eaten them she completely freaked out. After this I went through her dirty laundry a few times to find her panties and then I ate them. She was totally p*ssed off and left me, she said I was a weirdo and it was costing her a fortune in new panties. Now that I can't eat her panties anymore I have started sneaking into ladies changing rooms in swimming pools and gyms so I can steal their panties and eat them. If Im really desperate and cant get hold of worn panties I will steal them of washing lines and munch on them. I have to admit I get extremely turned on by eating the panties and always have a throbbing when I am doing this. I know I need help, I guess you could say I'm a pantieoholic, but there are no support groups or help lines that I can call for this problem, what should I do?
