Going to doctors for severe germ ocd, what outcome/therapy should I expect?

Highly effective. Current available medications, especially the selective serotonin re-uptake inhibitor meds such as prozac/zoloft/lexapro/celexa etc.. Are quite effective and safe. There are many others as well, and along with cognitive/behavioral therapy can be quite helpful in controlling your symptoms. It is a frustrating disease, but quite treatable. Best of luck to you.
History and status. Step one is for your doctor to understand your condition, both its history and current status. After that, he/she will make diagnosis and recommend a treatment plan. Part of that discussion will include therapeutic options and what outcome to expect. You should try to take things a step at a time. Big step already being made to see a doctor. Good move!
