To clarify, is the feeling more related to believing that everyone else is living their happy lives while your missing out or not able to do so?
I would keep going. When you stop doing what you would like to be doing on a daily basis because of OCD, the OCD wins. OCD loves to create lingering feelings that something must be wrong, or that you're somehow different from everyone else, because it tries to keep you isolated. To keep pushing through and doing what is important to you despite the OCD shows that you are strong and that you are really the one in control--not the OCD.
Ocd does this to me constantly on lingering feelings... very annoying.
