Okay, I'm not sure if this belongs here. But I have an obsession with gaining weight. So much that I'm always afraid to eat. I exercise and everything, but I'm still fat in my mind. Is this an Obsession from OCD? My therapist said that OCD can sometimes turn into an eating disorder.

Another obsession is with owning things. Once I get something I want in my mind, I HAVE to own it otherwise I will be very depressed. I have gone as far as trying to find a tailor to make a specific plushie for me because I could not find one to buy. Is this my OCD?
