@Anonymous Sertraline is an SSRI. Just know that SSRIs can usually take about three weeks to begin having an effect, and they can sometimes worsen anxiety in the first week or two. But it’s definitely worth it and can make life so much more bearable. SSRIs are great for lessening the severity of symptoms.
Since you are also asking about options other than medication, I think the most important thing is to accept that you’re going to have a tough time for a bit. Unfortunately, it is what it is. You are having a flare-up, and they can last for a surprisingly long time. I have had flare-ups that last for two weeks or so. You can do everything right, but the loop won’t immediately break. Yet, it’s still incredibly important to starve the OCD. I don’t know exactly how Somatic OCD presents itself, so here is a general guideline for OCD:
delay, delay, delay compulsions. Even a 15-minute delay is a huge win and can sometimes actually prevent a flare-up.
Do not engage with the storylines, no matter how convincing, ugly, or scary they might be.
Delaying compulsions and disengaging won't feel good at all for days. It will feel like you’re not making any progress, because you’re still feeling this way. But it takes time for your feelings to adjust to your new behavior. And all of a sudden, you’ll think: “What was I so worried about?”
In the spot you are in now, make life as easy as possible for yourself. Treat it like an illness, because it is one. That means setting boundaries and being self-compassionate, just like you would if you had a fever. Don’t be ashamed of being kind to yourself, either. I am talking about taking a few days off work, and staying in bed to watch your favorite show. Self-compassion also means listening to your body and fulfilling your needs.
You mentioned you’re moving, and that’s obviously a big change. You could ask yourself what that change means to you, because your OCD is reacting to something - what is it? What is it about missing family and friends that makes you distressed? Look inward and listen, and try to soothe your inner self. Would it help to spend more time with your family and talk about how the change is affecting you, or ask how they are feeling? Could it be fear of how you’re going to spend time with them after you move? Reassure yourself that everything is going to be fine, and promise yourself you’re going to find solutions to your needs. Remember that you can always move back, video call your mom, or make plans with your friends more often.
