Welcome to No More Panic, Wes
What was the maximum dose you took of each, and how long were you at that dose? OCD is the most treatment resistant of the anxiety disorders and it can need high antidepressant doses to get a response. They can also often make things worse at the beginning.
The kick-in clock probably only began running once you were on 75-100mg. Also, antidepressants typically take 3-12 weeks to kick-in with most seeing positive results in the 5-8 week window. It can take several weeks for dose increases to make a difference. How many weeks greatly varies from person to person, but allow at least a month.
