I know it doesn't make sense because you can't become a sociopath unless you were born that way, and schizophrenia and biopolar disorder don't just spontaneously occur. So, the worries are really irrational but that's the hallmark of OCD, right?

I think it's a part of the OCD to fear you are sick. It is a fear I live with constantly and it can cause me to worry way too much. I swear WebMD is the worst for someone like me. You type in some minor symptoms and you always have cancer or something worse. Education is helpful...just don't look for ways to be sick...easier said than done!

I have health anxiety along with the OCD. I don't stress about having another mental illness like Schizophrenia but I do constantly stress about having Cancer.
Also, you are correct having OCD does not lead to you becoming a Sociopath or a schizophrenic.

I have found that there are Primary and Secondary and many of the secondary problems, which are at the surface and easiest to detect and treat by professionals, are just symptoms/results of coping with the Primary problem.

I first went to mental health in 2012 with depression and anxiety and suidical thoughts. I got passed around that day to six different trainees/psychologists/psychiatrists for 1 hour each, where I repeated the same info over and over. I left that day with zoloft for depression and ativan for anxiety. The suicidal thoughts temporarily went away. I finally saw the same psychiatrist for more than one hour total and in early 2013 was diagnosed with Major Depressive Disorder, Social Anxiety Disorder, Agoraphobia with panic attacks, my self mutilation (cutting, tweezing, nail biting) was finally noticed and various dosage and medication changes thru 2013. Not sure if they are real diagnosis or not, but I was also told I was HSP (highly sensitive person) and ODD (oppositional Defiance disorder) due to law & legal problems. My problems kept getting worse and medications actually might have made my Primary problems even worse. On Jan.1, 2014, I quit taking all meds and scheduled appointment at Amen Clinic in Newport Beach. From 2/12-2/14, I underwent a ton of diagnostic testing including qEEG, 2 Spect brain scans and a dozen other questionnaire tests. I was diagnosed with ADD (non-hyperactive) with Frontal Lobe Syndrome. This dates back to my childhood and is a Primary problem. I am undergoing intense one-on-one therapy, entirely different medications that previously and I am getting better, slowly. I am sure I also have Autism Spectrum Disorder dating to childhood as a Primary, either high functioning HFA or probably Asperger's Syndrome.

I hope you are able to identify your Primary's and get treatment for them. Good luck!

When this all first started for me I spent every waking hour of the day and night googling and doing online quizzes to see if I had some sort of underlying mental health issue other than what I already knew about. I was convinced. It's just the OCD

Yup had your exact same obsessions too. Its just health OCD really. Your pretty much too old to be schizophrenic as it occurs normally in late teens early 20's. You wouldn't worry about being a sociopath if you were one, as most are ruthless business men or serial killers. Bi Polar you would know if you were because you would go days without sleeping and having bizarre beliefs ( delusional thinking ) then you would be severely depressed/suicidal. That other guy is right looking up the net for symptoms is the worst possible thing for OCD'ers as you can pick symptoms out and think you have everything.

I have always wanted to help others, so it's hard for me when these worries come up. It's like...what's changed?

OCD and depression are linked, but the other two will never link to the OCD. If it's pure OCD it will stay OCD. Schizophrenic and sociopathic symptoms are different from OCD. J

Well I saw my psychiatrist and he said I don't have schizophrenic traits and, honestly, if I had sociopathic tendencies I would have had them before the anxiety and I wouldn't be posting on this board.

Right?

In OCD our thoughts can create lies about many things. It's up to us to figure out which is the lie and which is reality. We have to know ourselves to know the line that divide reality and OCD. OCD creates a false reality most of the time because the thoughts become stuck, We must react to this OCD thoughts in such a way that the OCD goes to the background the the reality shows us the truth.
