Silly Girl-
You are far from psychotic, so don't let your mind play tricks on you. First of all you have to realize that these thoughts you have is your sub-concious minds way of saying, "hey. There's something bothering me and you're not dealing with it, so I've got something that will get your attention!" Your sub-concious is trying to get your attention by smacking you in the face with something that scares you so that you'll deal with why you're having these thoughts.
Lets think about this for a minute. Why do we have these thoughts? What purpose do they serve? First off, something is bothering you that you're not dealing with and your sub-concious knows it. Secondly, if you have thoughts or compulsions, you don't have to worry about what's really bothering you, all you have to do is think about your obsessions. It's sort of like reading a book to take your mind off of things. Your brain is using OCD to get you to think about and worry about something else so you don't have to deal with the real issues that are causing the OCD.
OCD is a response to stress and problems, it's your brains way of dealing with things. Some people drink. Some people do drugs. Some people take prescription medications. Some people withdraw from society. Some people jog. Some people workout. Some people do needle work. Some people go swimming. Fact is these are all ways to relieve stress and deal with problems, and these activities help take your mind off of things. Your minds way of taking your concious thought off of things is to have these images pop into your head so now you're not thinking about OCD and not what's really bothering you.
We are 1 and 2 of an estimated 1.5 million pepole in the United States that suffers from OCD. You're not alone, and you'll never be alone. Just remember that there are alot of other people that have the same thing you do, and you're not alone.
I would highly recommend that you seek out a good Cognitive Behavioral Therapist that specializes in OCD and anxiety disorders. Medication will help take the edge off, but medication should be used in conjuntion with good therapy.
Don't give up. Never give up. With therapy and medications you'll start to feel much better....
