The expression "bottle up" means to suppress or hold in strong emotions or feelings instead of expressing them. You can use this expression when someone is not expressing how they feel and keeping their emotions to themselves. For example, if someone is upset about something but they don't talk about it and instead keep it all inside, you can say that they are "bottling up" their feelings. It's important to express our emotions and not bottle them up because it can cause more problems in the long run.
