Is it normal to be obsessed with someone you like?
Mostly.Normal for most people
It’s common to think about someone you like a lot, especially when the feelings are new. It’s worth taking a step back if those thoughts are taking over your life or pushing you to ignore their boundaries.
When you have a crush, your brain can replay conversations, daydream, and look for little signs they might like you back. Lots of people get swept up in that for a while; it doesn’t mean anything is wrong with you.
The useful distinction is whether it’s fun and manageable or making it hard to focus, feel okay, or respect their privacy and boundaries. If it’s taking over, try giving yourself some space from checking their updates and putting attention back into friends and things you enjoy.
