I've been trying to read and I can't find much online

I've had 'phantom smells' - most of the time there is a source; someone has come back from a cigarette, cat litter tray near by, someone else points out the funky smell. But one that lasts with me is this tipex/paint smell I can smell once a day with a few days off. I thought it was because an office below mine was being worked on but I smell it still now and again. I have become so obsessed with this. So obsessed. I sniff all the time. Other times I'm scared to sniff. I know you all think I'm mad but I'm just scared now about this symptom.
