hi, i was diagnosed with ocd in jan 04 (had it since 03) and i know what you mean about everything being good around you but you cant enjoy it. Here is why i think that is...when everything is "good" we obsess about evrything because we get thoughts in our head like "things are too good right now, so something terrible must be around the corner" so we sit and "create" these problems in our minds....."good" is just never good enough.
i hope that made sence to you, i totally sympathize....if you need anything let me know
