I may have to be hospitalized because of my ocd... any tips on what to expect? ?

Be open and honest about your symptoms. Follow your treatment regime, even when it feels really hard. Communicate about your struggles, hesitations, and worries. And most importantly: be kind to yourself. Don’t let your internal dialogue beat you up. There’s nothing wrong with getting help, even intensive help. You deserve to get better and that means you deserve access to the best treatments possible.

This is going to vary fairly widely by country. If you are in the US and are going voluntarily, you can expect to be in a locked unit. You will see a clinician for a entrance assessment where they will ask you about your history. They will also change you out of any non-approved clothing and take anything that you could use to harm yourself. You will likely be in a private or 2 person same-sex bedroom. The unit will have a common space called a day room where you will spend most of your time. There may be other smaller rooms for private counseling or treatments.

please can you explain further?
