Hello, doctor.
I have been suffering from obsessive-compulsive disorder (OCD) for over ten years.
I am on medication, but when intrusive thoughts arise, I feel compelled to ask others for confirmation.
If I don’t ask, I can’t stop thinking about it all day and am unable to focus on anything else.
For example, a few days ago, I went to a convenience store to pay a bill, but they said they couldn’t connect to the system, so they couldn’t process the payment.
I asked if I could still buy something, and they said yes, so I went home.
However, once I got home, I kept thinking about whether I could get a receipt.
To confirm, I rode my scooter back to buy a bottle of rice wine and asked if they could issue a receipt.
They said they had just fixed the system, so I asked if that meant they couldn’t issue one before it was fixed.
They confirmed that was correct and said they would give me a temporary receipt and I could exchange it for an official invoice the next day.
I left, but halfway home, I remembered they mentioned "代打" (substitute), and I started to wonder if the receipt was typed.
I rode back to ask if it was handwritten, and they confirmed it was, using a pen.
I went home again, but if I didn’t clarify everything, I couldn’t stop thinking about it.
I know they think I’m strange, but I truly can’t help it, and I feel sorry for them.
The next day, another thought popped into my head: what time did the system failure start? I know it’s not my concern, but I couldn’t shake it off.
I ended up taking my payment slip back to the store to pay and ask about it, but the staff were different from the day before.
I still asked, and they said it was fixed by noon.
I knew that, but I asked how many hours the failure lasted, and they didn’t answer me.
Coincidentally, my payment slip’s barcode wouldn’t scan, and they told me to go to a nearby post office to pay.
Halfway there, I still needed to know how long the failure lasted, so I rode back to ask again.
They thought I was odd for asking such things.
One of the staff members was on leave, and the other was in a different store, so they weren’t sure.
Fortunately, after I insisted, one of the staff checked their phone and told me when the failure occurred, which finally put my mind at ease to ride home.
Otherwise, I would have spent the whole day fixated on that.
A few days later, I went to a supermarket, and while checking out, the customer in front of me returned a plate of meat that cost 230 NT dollars.
I heard the cashier mention it, but while riding home, I suddenly thought, “Was it 230 or 220?” I knew I heard it was 230, but I still didn’t clarify, which made me feel miserable.
I had to ride back to ask the cashier, and she confirmed it was 230 and asked if everything was okay.
Once I heard the answer, I could finally stop thinking about it.
I know asking others is wrong, which adds to my stress, especially since they are strangers.
Sometimes, I even call people to bother them with my questions multiple times.
I know others must think I have a problem, but I truly can’t help it.
I understand that what others think is not my concern, but when the thoughts come, I feel desperate if I don’t express them.
Almost every day is a struggle, but I don’t have the courage to end it; I can only endure one day at a time.
I used to take one tablet of Lexapro and one 0.5 mg of Risperidone, but recently I’ve been taking two tablets of Lexapro.
I want to ask if taking them on an empty stomach in the morning (since I don’t have breakfast) is less effective.
Would taking them after meals work better? Otherwise, when the intrusive thoughts come, I still end up doing foolish things.
I’m genuinely afraid of myself, but I just can’t stop asking others.
I really don’t know what to do.
