Hi Kyojin.
You don't say whether or not you were treated for your OCD while you were drinking, or whether or not you've continued being treated while sober.
Withdrawing from alcohol absolutely exacerbates any present psychiatric condition, and it can quickly spiral out of control if not treated. It simply isn't "just going to go away" on its own.
Many people who carry a psychiatric diagnosis into sobriety refuse treatment for a variety of reasons, and most of them have an extremely difficult time staying sober as a result.
If you haven't already done so, see your doctor and get a referral for a psychiatric consultation.
